# Appendix 1. General decisions You will find here the list of different general decisions and choices made during the build of the DFC Standard. It is ordered from the most recent one to the oldest one; some of these decisions may sound obsolete or not related to today's specifications but they can help understanding how we build them. * [Federation vs Syndication](/dfc-standard-documentation/dfc-use-cases/appendixes/general-decisions/federation-vs-syndication.md) * [Stateless or stateful?](/dfc-standard-documentation/dfc-use-cases/appendixes/general-decisions/stateless-or-statefull.md) * [Service granularity](/dfc-standard-documentation/dfc-use-cases/appendixes/general-decisions/service-granularity.md) * [Directionality](/dfc-standard-documentation/dfc-use-cases/appendixes/general-decisions/directionality.md) * [Identification and authentication](/dfc-standard-documentation/dfc-use-cases/appendixes/general-decisions/identification-and-authentication.md) * [Centralized or decentralized data storage](/dfc-standard-documentation/dfc-use-cases/appendixes/general-decisions/centralized-or-decentralized-data-storage.md) * [Metadata repository](/dfc-standard-documentation/dfc-use-cases/appendixes/general-decisions/metadata-repository.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.dfc-standard.org/dfc-standard-documentation/dfc-use-cases/appendixes/general-decisions.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
