At the heart of the Hypermedia protocol is the immutable data that is signed by authors and then distributed over IPFS
Aside from files/attachments, every Data Blob utilizes IPLD DAG-CBOR format to produce structured IPFS blocks identified by CID.
Here we introduce you to the Signed Data Blob and all of the data it can produce. Then you can reference the Protocol which builds on this knowledge to offer many different RPCs for exchanging the signed data and the interpreted results.
Resources
All mutable data in the Hypermedia ecosystem is either a Resource or a ChangeResource
Data Blob Definitions
Each of these Signed Data Blobs are objects with a "type" field that discriminates against the following types:
Ref — A "commit" to a Document in a certain location
Change — Describes an update or creation of Document content
Comment — A Resource that describes a comment
Capability — A Resource that gives permission from one account to another
Profile — Provides metadata for the Account
