When creating your tags, you will need to provide different elements, particularly the type.
To create a tag, it is mandatory to specify the type, but what does tag type mean?
Here, the choice depends on determining whether the tag being created is a tag that will subsequently be assigned to entities, data, or indicators.
Thus, if the tag is specified as a "entity" type tag, then you will only be able to assign this tag later to entities. In the same way, if you choose the tag as a data tag, then the tag list can only be assigned to data, just as for the indicator tag, it can only be assigned to indicators.
Example:
Here, the tag "Site" with values "Store", "Industrial", "Agency" and "Headquarters" can only be assigned to the entities of the project ⬇️
On the contrary, in the second image, the tag "Scope" can only be assigned to the different data present in the project repository ⬇️
Here is the article that specifies how to assign the different tags to your data or entities:
