For example, these records could contain health and medical information, ownership of property, vehicles, money, qualifications, birth/expiry of people and entities, land surveys, manufacturing information of vehicles and equipment, banking and commercial transactions, etc. Given the diversity of such information, this Building Block provides services useful to abstract the structure, linkages, and grouping of information into various records and collections such as financial, legal, medical, social, educational, commercial, etc., as needed. The Building Block provides the capability to capture, store, search, distribute, and present data with zero or minimal need for software development. It also maintains and reports logs of all operations taking place on database schemas and data. It contains various functional components, and data resources to abstract away all the details and complexity, and to expose capabilities as service-APIs to external Building Blocks/applications. The Digital Registries Building Block is an optional Building Block for other GovStack Building Blocks that have the need to store information. Any traditional database platform could be used alone or in combination with Digital Registries Building Block. The Digital Registries Building Block can operate as a standalone service and could be implemented as one centralized instance per domain, containing multiple registries in one instance, or many instances per domain, each database in its own server. ![Illustration 1- Digital Registries Building Block in GovStack sandbox](/files/HbiMtysmo5y2oKs97g7y) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://registries.govstack.global/2-description.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
