Terminology used within this specification.
| Term | Description |
|---|---|
Message
The Message is the main entity of communication in this Building Block, it holds all the necessary information to deliver the information to the Publisher or to the Subscriber/client, leaving just a track of delivery Logs with no personal data included. Messages follow a predefined protocol and policy for the chosen or predefined Communication channel. As a rule, the delivery mode of the Message is asynchronous.
Publisher
This is the originator of the Message, holding information about the content of the Message and the (meta) data regarding the Subscriber who will receive the Message. In other words, Messaging Building Block proxies/relays the Message received by a Communication channel to the proper Subscriber/client/person.
Subscriber
In the Publish and Subscribe use case, where the Publisher is relaying the Message into the hands of Messaging Building Block, that will in turn route it to the desired Communication channel, the Subscriber is the one who is listening to the relevant Message Room to receive the Message from the Publisher. The Subscriber has given consent to the Publisher to access or retrieve and store its data for the purpose of carrying out the Messaging event.
Messaging event
Messaging event is the (single) act of asynchronous information transfer between the Publisher and the Subscriber, consisting of the following steps: 1) secure identification and access management of the Publisher and the Subscriber; 2) access to and/or retrieval of relevant Subscriber data and consent for using the data from the Subscriber; 3) selection of relevant data transfer policy and protocol for the Messaging event; 4) Management and processing of Logs and relevant metadata during and after the Messaging event.
Messaging protocol
It is the protocol enabling the Messaging Building Block to communicate and transfer data between appropriate endpoints.
N.B. In its initial versions, GovStack Messaging Building Block is using Matrix/Elements protocol as a reference point for creating the GovStack Messaging Building Block protocol.
Communication channel
It is the endpoint of the Message delivery, the means used by the Publisher or the Subscriber to communicate. It can be a social media tool, e-mail or SMS service, or a distributed network.
Log
It holds track of Message delivery with the encrypted content to help with the maintenance and troubleshooting of the messaging services.
Routing Policy
Routing policy is the essential, configurable service of the Messaging Building Block, published in the Information Mediator Building Block, and is enabling the Publishers and the Subscribers to pre-define and use the appropriate Routing Policy for the particular Messaging event. In future iterations of this specification, the Routing Policy can be applied to the Messaging Rooms.
Service provider
Service providers provide service(s) to End clients. For example, medical doctors, hospitals, government agencies, etc. In some cases, a Service provider can also be in a role of an End client, being served by another Service provider.
End client
In most cases, End clients are citizens of any given country contacting and/or requesting or being served by a Service provider. For example, a mother/caretaker of a newborn child being serviced by a Health Care Service provider.
This section lists the technical requirements of this Building Block.
In addition to the functional requirements described in this section, GovStack's cross-cutting requirements defined in the architecture specification document and GovStack Security Requirements, apply.
The queuing process varies according to the policy and message type attached to the messaging, if an emergency messaging type applies to it, the messaging gets prioritized, otherwise, the FIFO algorithm (First In, First Out) applies to other message types. It saves all the requests for further processing, furthermore, works in the form of an "AS IS" process analysis without changing anything on the request. The message queueing mechanism will:
save a hash (MHASH) of the original request and a Unique Message ID (UMID);
respond with "Message received" to the sender with generated UMID.
Messaging requests go through a final check to be clean of defects and inconsistencies, to check with external systems as necessary:
check for message duplicates by making an actual request to a database to see if entries with MHASH and UMID exist;
low-level validation of data types and data completeness;
check for inconsistencies;
standard error messages and codes are used as a response to inconsistent requests.
In relation to batch logic, messages are scheduled against the availability of systems, throughput limitations, and rules set by programs.
Regular and repeat messages are scheduled.
Batches may be given prioritization in the queue according to the message settings.
The essential control logic may be included here specific to the individual batch sending and resending.
Additional workflow checks as required, including resending failed transactions.
Handles the initiation of input data processing from all the API messaging calls and makes the API access control verification from other Building Blocks to the Messaging Building Block and vice versa as well as within the Messaging Building Block, it will:
use Identity and access management for authentication;
perform input validation checks to prevent oversized message attacks, SQL injection attacks as well as JSON and XML threats;
require authentication for all API users;
manage access quotas and throttling;
logging of all API calls made;
allow API providers to limit the rate of consumption for all API users;
transform backend error messages into standardized messages so that all error messages look similar (this also eliminates exposing the backend code structure).
This request could come from two sources: external or internal. An external source could be another GovStack Building Block (e.g. the Registration Building Block). Either source must be appropriately authenticated and authorized to initiate the request. The request must contain at a minimum: the contact address (email, phone number, etc.), the message type, the content of the message, and the initiating source’s unique transaction ID.
Find unprocessed requests from a database.
Prepare each request for actual processing, requests may come as single or batch messages and every message needs to be treated as a separate entry.
It prepares unprocessed requests for actual processing.
Each component of the messaging building block should be capable of producing transaction logs. This is important to ensure that the system can be adequately monitored and troubleshooting can be performed efficiently and effectively.
The components should also generate transaction logs for events that capture at least the following information:
transaction date and time;
transaction source;
transaction destination;
supplementary data;
transaction status (success, failed, in progress).
The event logs and the transaction logs should NOT capture any sensitive data such as contact data, or channel authorization credentials.
Fetch and securely archive logs from working nodes is also expected.
This section lists the technical capabilities of the Messaging Building Block. The following components are needed to achieve the technical functionalities of the messaging Building Block.
The Messaging Building Block is part of the GovStack implementation and is prompted to open up a two-way communication channel to deliver and capture messages/data between the GovStack systems and the end users, physical and legal persons.
As a rule, the Messaging Building Block does not own any information but is carrying the minimum amount of (meta) data needed to transfer/publish a message. Messaging Building Block allows other Building Blocks and applications to reach out to customers/citizens in order for them to be able to make a decision or access a service. This Building Block can also be used for broadcasting a disaster message.
Messaging policies are configurable modalities and channels that can be accessed/utilized through the Messaging Building Block in order to reach out to the users or groups. This Building Block is using existing applications/channels, such as e-mail, SMS, and messaging platforms for enabling users to subscribe to an application/channel provided by Messaging Building Block itself for text-based content.
Having published its messaging policies and services at the Information Mediator Building Block, the other Building Blocks and applications can discover and use the services of the Messaging Building Block.
Messaging Building Block allows for asynchronous communication, using either point-to-point communication or a Pub/Sub model (using Information Mediator Building Block) where the user is subscribed to a message room/group and will be receiving all messages intended for the “mother of newborn child” group.
Security: Before allowing any messages to be published, the Messaging Building Block fetches a corresponding ID and a role or a session token available for the user for authentication and access purposes. Incorporates privacy into its design when the purpose of the authentication is not revealed if a service provider sends an authentication request.
Developed by Rainer Türner (Information System Authority of Estonia), Magnus Hult (Element.io), John Cordeiro and Martin Karner (Estonian ICT Cluster), Bramhanand Jha (India's National e-Governance Division)
This section provides context for this Building Block.
The Messaging Building Block provides a standardized, secure communication channel between GovStack service providers and end customers (in most cases citizens). By using GovStack Messaging Building Block, service providers rely on the building block's central functionalities, logging, back upping, security features, etc. without the need to reproduce and maintain them by themselves.
For greenfield developments, it helps developers build communication components on top of different GovStack services, to make use of federated architecture when passing messages, including machine- and human-triggered (both synchronous and asynchronous) ones.
Messaging Building Block is a standalone messaging gateway/client/proxy (including all possible modalities: email, SMS, etc.), but can also facilitate connections with existing messaging service providers, hence making the adoption process less disruptive for end users.
This Building Block can be used for messaging events in many different applications and use cases, such as:
Example A, encrypted: after being enrolled into a Health Care Program for the mothers of a newborn child, a woman/caretaker receives a message from the Health Care Service Provider about a doctor's appointment. The message is routed to an existing communication channel/application, in use and provided by the mother.
Example B, unencrypted: a reminder/notification message from the service provider to the mother about the same appointment. If a doctor decides to hold the consultation remotely, a link is sent to the mother and a video consultation is started (the conference is started and users join the room). The event is triggered by the Scheduler Building Block component and a new message is processed to the client.
Example C: a user-initiated message regarding a doctor consultation, targeted to a Health Care Provider's phone number or a chatbot URL (universal or targeted messaging back to the system).
Messaging Building Block is enabling signing up for and receiving services, such as:
mother and childcare;
social care;
receiving entitlements from the government;
opening bank accounts;
communicating disaster messages or reminders about the voters' rights during elections;
etc.
Communication between different government services (government to government) is out of the scope of this Building Block but can be enabled through the Information Mediator Building Block.
Scheduling messages according to some business logic is out of the scope of this Building Block because is done by Scheduler Building Block.
Processing of incoming message content to apply some business logic.
Fully offline and no internet connection scenarios.
Real-time video and audio conferencing.
This section provides information on the core data structures/data models that are used by this Building Block.
The resource model shows the relationship between data objects that are used by this Building Block.
7.2.1.1 Person
Each model schema MUST have a corresponding JSON Schema (API definition file).
This section provides a reference for APIs that should be implemented by this Building Block.
This section provides a reference for APIs that should be implemented by this Building Block. The APIs defined here establish a blueprint for how the Building Block will interact with other Building Blocks. Additional APIs may be implemented by the Building Block, but the listed APIs define a minimal set of functionality that should be provided by any implementation of this Building Block.
The provides additional information on how 'adaptors' may be used to translate an existing API to the patterns described here. This section also provides guidance on how candidate products are tested and how GovStack validates a product's API against the API specifications defined here.
The tests for the Messaging Building Block can be found in
This API is designed to send out emails one by one.
Although an email can be sent to multiple recipients by using email, emailCC and emailBCC appropriately, this is still considered as sending a single email.
As a Doctor working in a hospital, I want to notify my patient about a confirmed registration so that the patient would know when to come for a visit.
This API is designed to send out identical emails to multiple (batch) recipients at once.
As a Hospital I want to notify a specified group of my clients about the possibility to register to vacant time slots within a limited period of time so that the clients potentially needing it the most would have a guaranteed chance to get an appointment
This API is designed to accept responses to emails that have been previously sent out by using the Messaging Building Block. The protocol itself is lightweight and expects custom services from anyone using it. The Messaging Building Block is responsible for delivering the message and does not know (or want to know) anything about the content of it, how it will be used, etc.
As a Hospital, I want to get and send responses from and to clients so that I could continue and keep track of email conversations taking place via GovStack
This API is designed to provide information about the status of emails sent to the Messaging Building Block.
As a Doctor working in a hospital I want to know which emails I have sent haven't reached their destination so that I could contact such patients by using different means
Possible status of emails that can be queried are as follows:
scheduled
processing
deferred
bounced
not sent
delivered
There is no keeping track of emails which have been sent successfully, as this would end up creating and maintaining a massive database of emails, their senders and recipients, etc., which would be wrong for so many reasons.

This section will highlight important requirements or describe any additional cross-cutting requirements that apply to this Building Block.
The cross-cutting requirements described in this section are an extension of the cross-cutting requirements defined in the architecture specification document. Any implementation MUST adhere to all requirements from GovStack Security Requirements.
There are two main reasons for using denormalized databases instead of traditional normalized databases. First, to significantly improve the performance of read queries. This is highly important as databases of the Messaging Building Block will be under a heavy load of requests that in many cases are expected to respond near real-time. Second, to be able to export the content of databases in the format of time-series databases (see below for its reasons). To achieve this, using "UPDATE" and "DELETE" queries in SQL commands SHOULD be disabled. If not, they MUST be avoided by developers and caught by automated tests if still used.
By having this capability, it is possible to delete the content of processed data from production-level server databases right after they have been securely archived. This is important to reduce the impact of potential data breaches by security incidents of potentially N number of application servers hosted by different parties.
If done so, using archived datasets, either fully or partially, allows to recover and/or re-engineer lost databases (or just datasets of interest) automatically and in a matter of seconds if such pipelines have been predefined. Also, by converting the content of relational databases into a format of time-series databases, these purely text-based datasets are easily usable by different kinds of databases, analytics tools, etc., not just by the relational database used at first.
Technical components (with the exception of relational databases) must be stateless in the sense of the Service statelessness principle.
At least on the level of active-passive nodes based on the principle of "eventually consistent". Pending: initial state for all messages waiting to be queued.
Queued: messages that are in the queue to be sent.
Sent: messages with proper confirmation that was sent to the provider.
Delivered: messages with proper confirmation that was delivered to the end-user.
Errored: messages with an error during delivery.
Failed: messages that are errored and we gave up sending.
If Messaging Building Block protocols are followed, the technical stack used to provide messaging as a service is vendor-neutral, meaning that anyone is free to use technical solutions of their own choice.
Only allowed participants are allowed to provide and use the services of Messaging Building Block.
Messaging Building Block is a dumb messaging proxy that gets all of its relevant input from its clients. This also includes the names and contact information of all relevant participants. Such sensitive information may not exist in its raw and/or re-engineerable form nor in databases or logs.
Depending on the specific use case, this may mean end-to-end encryption or SNI routing.
Every instance of a service must generate audit logs containing information about all of its actions regarding timestamps, related parties, identifiers to operations performed, and HTTP response codes for any given action. Audit logs may not contain the actual content of the message. Audit logs must be in a time series database format. Audit logs must be accessible by a given endpoint by the central service provider only. Audit logs should be periodically removed from their original source after a defined period of time.
All APIs are exposed via secure socket connections (HTTPS).
Manage access quotas and throttling.
Logging of all API calls made.
Allow API providers to limit the rate of consumption for all API users.
Transform backend error messages into standardized messages so that all error messages look similar; this also eliminates exposing the backend code structure.
Contact address (email, phone number, etc.), the message type, the content of the message, and the initiating source’s unique transaction ID.
Asynchronous messaging processing. OpenAPI specifications for calling this function; resource models and data structures, internal and external interfaces.
Stateless architecture.
Message broker tool to enable performant queueing mechanisms such as RabbitMQApache/Kafka, or GRPC for data transfer speed purposes.
Databases with unstructured data should be treated with Elasticsearch/Logstash.
End users should be registered as Message queue clients/subscribers in the Messaging Building Block. Subscription is required to receive a message.
In order to prevent single points of failure, messages must be replicated on at least 2 different service providers. In case of message replication, all unprocessed replicated messages must be kept track of and relevantly updated in order to prevent re-processing them.
Admin of the room must be able to choose the policy profile with the configuration of the message provider, e.g. retrial frequency.
Unsent and unsuccessfully delivered messages must remain in a queue until being successfully delivered or otherwise permanently processed.
Pending (initial state for all messages waiting to be queued); Queued (messages that are in the queue to be sent); Sent (messages with proper confirmation that was sent to the provider); Delivered (messages with proper confirmation that was delivered to the end-user); Errored (messages with an error during delivery); Failed (messages that are errored and we gave up sending).
Messages not delivered in a period of 24 hours (any errored or queued messages more than 24 hours old must be labeled as failed and go out of the queue); Messages retrial (Errored messages must be retried for 24 hours).
Client applications must send authorization tokens in the authorization header of the request to authenticate users and the API Management Gateway will verify whether the token is valid.
Perform input validation checks to prevent oversized message attacks, SQL injection attacks as well as JSON and XML threats.
The following standards are applicable to data structures in the Messaging Building Block:
All services are provided as REST API requests
Only Transport Layer Security (TLS) Server Name Indication (SNI) extension-compatible requests are allowed
REST APIs calls and responses use JSON as the only allowed data format.
Using ISO 8601 on dates and times
UTF-8 character encoding on text input
Key Digital Functionalities describe the core (required) functions that this Building Block must be able to perform.
The Messaging Building Block is a standalone messaging gateway/client/proxy (including all possible modalities: email, SMS, etc.) but can also facilitate connections with existing messaging service providers by enabling safe communication. The communication in this Building Block can be categorized in two different directions as follows:
In scope of v1
informing End clients about their registration;
reminding and requesting End clients' confirmation for appointment booking or other events;
getting confirmation about government services and interactions.
In scope of future releases
delivering information at scale to End clients;
alerting End clients in emergency contexts.
In scope of v1
confirm Client registration for a service;
providing data to the government/service.
In scope of future releases
asking for information about government services.
This section provides a detailed view of how this Building Block will interact with other Building Blocks to support common use cases.
A workflow provides a detailed view of how this Building Block will interact with other Building Blocks to support common use cases.
This section lists workflows that this Building Block must support. Other workflows may be implemented in addition to those listed.
The main prerequisite for Person-to-Building Block communication is that there is an existing Sender/Source Building Block with the following properties:
the relevant credentials and details about the Person/Citizen to be addressed with;
the content of the message and a reference to a communication channel (contact details) to be used;
additionally, the service discovery service at the Information Mediator Building Block needs to be active. Information Mediator Building Block publishes the list of available services of the Messaging Building Block to the source GovStack Building Block, i.e. Workflow.
A reference token should be carried throughout the communication session in order to save a point of reference for reverse communication back from the Person to the Building Block. In other words, the main prerequisite for Person-to-Building Block communication is the availability of a communication channel and a reference token.
This generic workflow is used to transfer messages between GovStack Building Block and the end user, Person. Data is submitted from a GovStack Building Block front-end application. This workflow shows a connection to GovStack Building Block (such as a government Health System Application) to convey a message that is associated with a real person.
This workflow requires interaction with the Information Mediator Building Block and a source GovStack Building Block, for example, a Health Care Service Building Block or registry Building Block.
The sequence diagram shows the flow of data between Building Blocks for this workflow.
The following diagram illustrates the internal processes of the Messaging BB to send messages received as external requests and sent via external service providers.

User Journey
Use Case
Capability
Functional Requirements
Technical Requirements
Post-partum mother and child care
Mother Registration
Inform the mother about registration through different modalities (SMS[1] , email, WhatsApp, Voice message etc.).
See the functional requirements and technical requirements.
Workflow, preconditions such as phone number/contact.
The user needs to register/connect its contact data to the Messaging Building Block (mailID, phone no etc)[2] [3] [4] or another Building Block.
For example, a) direct MSG Type (Emergency) has concrete API endpoints, blasting all channels/endpoints. Business logic and policy in separate Building Blocks can add MSG type, address: who-to-send-to, MSG channel etc.
In reverse communication, a unique identifier is created per user upon registering at the Messaging Building Block.[5] [6] Allowing push and pull models. To be able to understand and apply a routing policy in the particular Application,enabling the Messaging Building Block for routing the Message [7] [8] through specific channels [9] [10] and graceful degradation.
OpenAPI specifications for calling this function; resource models and data structures; [11] internal and external interfaces.
Stateless architecture.[12] Microservices require Rabbit MQ; Apache/Kafka or GRPC[13] [14] for data transfer speed purposes. Databases with unstructured data should be treated with Elasticsearch/Logstash. [15] [16]
Similarly to the client-to-client pubsub model also the end users can be registered as Message queue clients/subscribers in the Messaging Building Block. Subscription is required to receive a message.[17] [18] The message is put in the queue and communicated to the other Building Blocks[19] [20].
Mother confirmation of a child registration
Mother receives a confirmation registration message with a token that identifies that event for future interactions.
Appointment booking
Asking the mother for the booking confirmation of a doctor or vaccination appointment through different communicable channels (SMS, email, WhatsApp, Voice message, etc.).
Appointment reminder
Reminding the mother about the booking.

Name
Messaging - Postpartum and infant care (Configuration).
Description
The use case implements configuration of a Messaging Gateway in infant care use case scenarios. This results in a saved configuration to be issued to all mothers requiring infant care.
Trigger (the event that triggers the use case)
The (healthcare) application admin/user wishes to configure the policies and assign user contact details associated with the Messaging service.
Any change in the pre-condition that requires a re-configuration.
Preconditions (list of conditions that MUST be met in order for the use case to be successful)
The application admin/user is logged into the system and has sufficient privileges to use the system.
A Messaging Policy exists, based on existing electronic data handling laws and regulations.
Assumption: The mother is in possession of a digital communication device and an application, capable of receiving and sending messages.
Assumption: Government/GovStack implementation has an agreement and API GW with the service providers for transmitting text and voice messages, setting up conference calls.
Data inputs
Existing data policies relevant to the messaging scenario.
Contact information of end users accessed in another system or[21] [22] transmitted along the Messaging Request by another GovStack Building Block./Application.
Any legal information, standards.
Actors (a person, a company or organisation, a computer program, or a computer system - hardware, software, or both)
The application admin/user who configures the messaging policy (a person, IT admin)
The health-care provider application (a computer system).
Data Protection Officer, Auditors (A person, or an independent authority).
GovStack application (HealthCareProvider Application, Workflow, Information Mediator) triggers a Message to be sent with an appropriate policy metadata.
Information Mediator publishes the services of the Messaging Building Block for the other Building Block to use (with available policies). When another Building Block discovers Messaging, it receives X number of policies. Metadata says which policy to pick and where to route it to.
Note from the Information Mediator: in order to make your Building Block service available on GovStack, you have to register those services (Open API specs and have a specific business agreement signed between the parties/applications/services).
Normal Course (what happens if the event is triggered and the preconditions have been met)
The Messaging Building Block application user is able to invoke the configuration workflow.
The healthcare application user uses the existing Messaging Building Block policy and relevant metadata about the user for registering for postpartum and infant care. This policy could be signed off by the organisation's Data Protection Officer, for example:
The data required are:
Usage purpose.
Data policies and rules.
Define what data is being collected.
The configuration is saved.
Once the DPO approves, the configuration is published toward the end-use case, i.e. Healthcare Professional registration system.
Alternative Course (links to other use cases in case there are different ways how to solve the same use case)
Data configuration error scenarios.
Data Protection Officer disapproves and the configuration is re-submitted for review and approval.
Data output
The Messaging Building Block policy configuration data.
Post-Conditions (the success criteria)
The Messaging policy is saved in the system and is published in the Information Mediator, making it available for use in the registration process.
The system is now configured and ready for routing messages during a workflow.
Exceptions (error situations)
In case the policy has not been configured, an error message is displayed and communicated back to the system that made the request.
Related Building Blocks (related to that particular use case)

Appointment booking confirmation, where there are two levels of confirmation:
Immediate confirmation: I have received the message.
I have deposited a message, and have given the message a token number. And on the basis of this, I can pick up the message or a reply later.
Reminder message is already there and an event will trigger it.
Event notification, trigger: for example: please join the call.
This service may reside on both Messaging BB's and client's side. If used, a matching OpenAPI spec must be provided by the service provider, describing the expected input when making request to the endpoint.
