Github Schema¶

GitHubRepository¶

Representation of a single GitHubRepository (repo) repository object. This node contains all data unique to the repo.

Field	Description
firstseen	Timestamp of when a sync job first created this node
lastupdated	Timestamp of the last time the node was updated
id	The GitHub repo id. These are not unique across GitHub instances, so are prepended with the API URL the id applies to
createdat	GitHub timestamp from when the repo was created
name	Name of the repo
fullname	Name of the organization and repo together
description	Text describing the repo
primarylanguage	The primary language used in the repo
homepage	The website used as a homepage for project information
defaultbranch	The default branch used by the repo, typically master
defaultbranchid	The unique identifier of the default branch
private	True if repo is private
disabled	True if repo is disabled
archived	True if repo is archived
locked	True if repo is locked
giturl	URL used to access the repo from git commandline
url	Web URL for viewing the repo
sshurl	URL for access the repo via SSH
updatedat	GitHub timestamp for last time repo was modified

Relationships¶

GitHubUsers or GitHubOrganizations own GitHubRepositories.

(GitHubUser)-[OWNER]->(GitHubRepository)
(GitHubOrganization)-[OWNER]->(GitHubRepository)

GitHubRepositories in an organization can have outside collaborators with different permissions, including ADMIN, WRITE, MAINTAIN, TRIAGE, and READ (Reference).
```
(GitHubUser)-[:OUTSIDE_COLLAB_{ACTION}]->(GitHubRepository)
```

GitHubRepositories use ProgrammingLanguages

(GitHubRepository)-[:LANGUAGE]->(ProgrammingLanguage)

GitHubRepositories have GitHubBranches

(GitHubRepository)-[:BRANCH]->(GitHubBranch)

GitHubTeams can have various levels of access to GitHubRepositories.

(GitHubTeam)-[ADMIN|READ|WRITE|TRIAGE|MAINTAIN]->(GitHubRepository)

GitHubOrganization¶

Representation of a single GitHubOrganization organization object. This node contains minimal data for the GitHub Organization.

Field	Description
firstseen	Timestamp of when a sync job first created this node
lastupdated	Timestamp of the last time the node was updated
id	The URL of the GitHub organization
username	Name of the organization

Relationships¶

GitHubOrganizations own GitHubRepositories.

(GitHubOrganization)-[OWNER]->(GitHubRepository)

GitHubTeams are resources under GitHubOrganizations
```
(GitHubOrganization)-[RESOURCE]->(GitHubTeam)
```
GitHubUsers are members of an organization. In some cases there may be a user who is “unaffiliated” with an org, for example if the user is an enterprise owner, but not member of, the org. Enterprise owners have complete control over the enterprise (i.e. they can manage all enterprise settings, members, and policies) yet may not show up on member lists of the GitHub org.
```
(GitHubUser)-[MEMBER_OF|UNAFFILIATED]->(GitHubOrganization)
```

GitHubTeam¶

A GitHubTeam organization object.

Field	Description
firstseen	Timestamp of when a sync job first created this node
lastupdated	Timestamp of the last time the node was updated
id	The URL of the GitHub Team
name	The name (a.k.a URL slug) of the GitHub Team
description	Description of the GitHub team

Relationships¶

GitHubTeams can have various levels of access to GitHubRepositories.

(GitHubTeam)-[ADMIN|READ|WRITE|TRIAGE|MAINTAIN]->(GitHubRepository)

GitHubTeams are resources under GitHubOrganizations
```
(GitHubOrganization)-[RESOURCE]->(GitHubTeam)
```

GitHubUser¶

Representation of a single GitHubUser user object. This node contains minimal data for the GitHub User.

Field	Description
firstseen	Timestamp of when a sync job first created this node
lastupdated	Timestamp of the last time the node was updated
id	The URL of the GitHub user
username	Name of the user
fullname	The full name
has_2fa_enabled	Whether the user has 2-factor authentication enabled
role	Either ‘ADMIN’ (denoting that the user is an owner of a Github organization) or ‘MEMBER’
is_site_admin	Whether the user is a site admin
is_enterprise_owner	Whether the user is an enterprise owner
permission	Only present if the user is an outside collaborator of this repo. `permission` is either ADMIN, MAINTAIN, READ, TRIAGE, or WRITE (ref).
email	The user’s publicly visible profile email.
company	The user’s public profile company.

Relationships¶

GitHubUsers own GitHubRepositories.

(GitHubUser)-[OWNER]->(GitHubRepository)

GitHubRepositories in an organization can have outside collaborators with different permissions, including ADMIN, WRITE, MAINTAIN, TRIAGE, and READ (Reference).
```
(GitHubUser)-[:OUTSIDE_COLLAB_{ACTION}]->(GitHubRepository)
```
GitHubUsers are members of an organization. In some cases there may be a user who is “unaffiliated” with an org, for example if the user is an enterprise owner, but not member of, the org. Enterprise owners have complete control over the enterprise (i.e. they can manage all enterprise settings, members, and policies) yet may not show up on member lists of the GitHub org.
```
(GitHubUser)-[MEMBER_OF|UNAFFILIATED]->(GitHubOrganization)
```

GitHubBranch¶

Representation of a single GitHubBranch ref object. This node contains minimal data for a repository branch.

Field	Description
firstseen	Timestamp of when a sync job first created this node
lastupdated	Timestamp of the last time the node was updated
id	The GitHub branch id. These are not unique across GitHub instances, so are prepended with the API URL the id applies to
name	Name of the branch

Relationships¶

GitHubRepositories have GitHubBranches.

(GitHubBranch)<-[BRANCH]-(GitHubRepository)

ProgrammingLanguage¶

Representation of a single Programming Language language object. This node contains programming language information.

Field	Description
firstseen	Timestamp of when a sync job first created this node
lastupdated	Timestamp of the last time the node was updated
id	Language ids need not be tracked across instances, so defaults to the name
name	Name of the language

Relationships¶

GitHubRepositories use ProgrammingLanguages.

(ProgrammingLanguage)<-[LANGUAGE]-(GitHubRepository)

Dependency::PythonLibrary¶

Representation of a Python library as listed in a requirements.txt or setup.cfg file. Within a setup.cfg file, cartography will load everything from install_requires, setup_requires, and extras_require.

Field	Description
id	The canonicalized name of the library. If the library was pinned in a requirements file using the `==` operator, then `id` has the form `{canonical name}\|{pinned_version}`.
name	The canonicalized name of the library.
version	The exact version of the library. This field is only present if the library was pinned in a requirements file using the `==` operator.

Relationships¶

Software on Github repos can import Python libraries by optionally specifying a version number.
```
(GitHubRepository)-[:REQUIRES{specifier}]->(PythonLibrary)
```
- specifier: A string describing this library’s version e.g. “<4.0,>=3.0” or “==1.0.2”. This field is only present on the :REQUIRES edge if the repo’s requirements file provided a version pin.
A Python Dependency is affected by a SemgrepSCAFinding (optional)
```
(:SemgrepSCAFinding)-[:AFFECTS]->(:PythonLibrary)
```
