Tags

Tags are attributes of an artifact, i.e., a class, a name, names of artifact's parts, etc... The list of artifact tags vary across artifact's classes. To learn more about artifacts visit archivist-package.

Details

Tags are attributes of an artifact. They can be the artifact's name, class or archiving date. Furthermore, for various artifact's classes more different Tags are available.

A Tag is represented as a string and usually has the following structure "TagKey:TagValue", e.g., "name:iris".

Tags are stored in the Repository. If data is extracted from an artifact then a special Tag, named relationWith is created. It specifies with which artifact this data is related to.

The list of supported artifacts which are divided thematically is presented below. The newest list is also available on archivist wiki on Github.

Note

In the following way one can specify his own Tags for artifacts by setting artifact's attribute before call of the saveToLocalRepo function: attr(x, "tags" ) = c( "name1", "name2" ), where x is an artifact and name1, name2 are Tags specified by a user. It can be also done in a new, simpler way by using userTags parameter like this:

  • saveToLocalRepo(model, repoDir, userTags = c("my_model", "do not delete")).

Specifing additional Tags by attributes can be beneficial when one uses addHooksToPrint.
