A "tag" is a keyword that you can attach to your resources to classify them. A tag can be attached to multiple resources, and a resource can have multiple tags. Each tag, sometimes called "label" or "keyword", is simply defined by its name, which expresses a notion specific to a project. This mechanism allows a powerful classification, transversal to a project.
The following list provides sample tags frequently encountered: organization, meeting, software, 2018, 2019, spreadsheet, english, data, environment, communication ...
If you have a wiki page about an environmental meeting in 2019, you can attach tags [meeting, environment, 2009 ]. For a spreadsheet in English, you could choose [spreadsheet, environment, english].
Resources have a simple interface that allows you to check the tags or to add new ones. To allow a quick identification, each tag has a fixed color code.
The easiest way to create a new tag is to add it to the list of tags for a resource. It is also possible to create new tags from the configuration of a project.
By clicking on the button Search and then on the tab "by tags", you will be able to search in your project for "tagged" resources with a given selection.
It is possible to delete a tag from the configuration of a project.
It depends on the project, usually it will take between 10 and 20 tags in a project to correctly organize all documents. Each document will then usually have 3 or 4 tags. If your collection of tags is well organized, a search specified by 3 or 4 tags will return only a handful of documents, all relevant. In mathematics terms, we know for example that there are 4845 distinct combinations of 4 tags taken from a collection of 20 tags, which will generally be sufficient to accurately classify documents in a large project.
