title: ForgeFed Vocabulary

Abstract

This document describes the ForgeFed vocabulary. It's intended to be an extension of the ActivityPub Vocabulary and provides additional vocabulary for federation of project management and version control system hosting and collaboration platforms.

Introduction

The ForgeFed Vocabulary describes a set of types and properties to be used by platforms that support the ForgeFed protocol. This specification describes only the new vocabulary called ForgeFed. The ForgeFed behavior specification describes how to use this vocabulary, along with standard ActivityPub vocabulary, to support the ForgeFed protocol.

Types

The base URI of all ForgeFed terms is https://forgefed.peers.community/ns#. The ForgeFed vocabulary has a JSON-LD context whose URI is https://forgefed.peers.community/ns. Implementers MUST either include the ActivityPub and ForgeFed contexts in their object definitions, or other contexts that would result with the ActivityPub and ForgeFed terms being assigned they correct full URIs. Implementers MAY include additional contexts and terms as appropriate.

A typical @context of a ForgeFed object may look like this:

"@context": [
    "https://www.w3.org/ns/activitystreams",
    "https://forgefed.peers.community/ns"
]

Activity Types

Push {#act-push}

URI: https://forgefed.peers.community/ns#Push

Notes: Indicates that new content has been pushed to the Repository.

Extends: Activity

Example:

Actor Types

Repository {#type-repository}

URI: https://forgefed.peers.community/ns#Repository

Notes: Represents a version control system repository.

Extends: Object

Example:

{
    "@context": [
        "https://www.w3.org/ns/activitystreams",
        "https://w3id.org/security/v1",
        "https://forgefed.peers.community/ns"

}

Object Types

Branch {#type-branch}

URI: https://forgefed.peers.community/ns#Branch

Notes: Represents a named variable reference to a version of the Repository, typically used for committing changes in parallel to other development, and usually eventually merging the changes into the main history line.

Extends: Object

Example:

{
    "@context": [
        "https://www.w3.org/ns/activitystreams",
        "https://forgefed.peers.community/ns"

Commit {#type-commit}

URI: https://forgefed.peers.community/ns#Commit

Notes: Represents a named set of changes in the history of a Repository. This is called "commit" in Git, Mercurial and Monotone; "patch" in Darcs; sometimes called "change set". Note that Commit is a set of changes that already exists in a repo's history, while a Patch is a separate proposed change set, that could be applied and pushed to a repo, resulting with a Commit.

Extends: Object

}

For examle, if items lists items in reverse chronogical order, then so does earlyItems.

committedBy {#prop-committedby}

URI: https://forgefed.peers.community/ns#committedBy

Notes: Identifies the actor (usually a person, but could be something else, e.g. a bot) that added a set of changes to the version-control Repository. Sometimes the author of the changes and the committer of those changes aren't the same actor, in which case the committedBy property can be used to specify who added the changes to the repository. For example, when applying a patch to a repository, e.g. a Git repository, the author would be the person who made the patch, and the committer would be the person who applied the patch to their copy of the repository.

Domain: Commit

Range: Object

Functional: Yes

Inverse of: (None)

Example:

hash {#prop-hash}

URI: https://forgefed.peers.community/ns#hash

Notes: Specifies the hash associated with a Commit, which is a unique identifier of the commit within the Repository, usually generated as a cryptographic hash function of some (or all) of the commit's data or metadata. For example, in Git it would be the SHA1 hash of the commit; in Darcs it would be the SHA1 hash of the patch info.

Domain: Commit

Range: xsd:string of hexadecimal digit ASCII characters

Functional: Yes

Inverse of: (None)

Example:

committed {#prop-committed}

URI: https://forgefed.peers.community/ns#committed

Notes: Specifies the time that a set of changes was committed into the Repository and became a Commit in it. This can be different from the time the set of changes was produced, e.g. if one person creates a patch and sends to another, and the other person then applies the patch to their copy of the repository. We call the former event "created" and the latter event "committed", and this latter event is specified by the committed property.

Domain: Commit

Range: xsd:dateTime

Functional: Yes

Inverse of: (None)

Example:

filesAdded {#prop-filesadded}

URI: https://forgefed.peers.community/ns#filesAdded

Functional: No

Inverse of: (None)

Example:

ref {#prop-ref}
