Tags in Gramps/tr
Tags are markers that can be applied to selected objects in Gramps. They allow the tagged objects to be filtered. And the Tag color can be used to color code rows in list view and to mark some charts.
For people using Gmail or Thunderbird, the Tag feature will seem familiar. Instead of classifying emails into folders like in Outlook (in Windows) or Evolution (in Linux), emails are classified by assigning tags to them. So instead of having a disjoint N:1 classification (a email can be in one and only one folder, and a folder can contain many emails), in Gmail or Thunderbird there is a N:M classification (a email can have several tags, and a tag can be applied to several emails)
Likewise, when you have a big tree, you might want to make subsets of the tree, and these subsets might be overlapping. For example, the subsets of your fathers family and your mothers family, some subset of your family that emigrated to Australia. The idea is to assign a different tag to each subset: Paternal, Maternal, Australia and ToDo for example.
Markers were the original implementation for this functionality in Gramps. They were much like the folders for emails. A person could be given at most one marker. Tags are thus like multiple-valued markers.
Tags and filters will both identify subsets of the tree. However, they have practical differences in usage. Specifying your father's family using filters is an easy thing; there are already Ancestor filters based on some rules built-in to do this. On the other hand, specifying the people that emigrated to the USA is harder. And filtering for the famous people in your family is simply impossible --- there is no logical rule for such a subjective characteristic. Creating a 'Famous' Tag is much more practical for such a purpose. However, filters have the advantage of being dynamic. When you add an ancestor of your father in the database, that ancestor will be automatically discovered by an Ancestor filter focused on your father. On the other hand, tags have no such automation. When adding a famous person in the tree, you would have to explicitly Tag them as FAMOUS.
- The most immediate object that comes to mind are the individuals, and that is also the most useful. However, other objects could be tagged:
- Places: For example "places to visit",
- Source: For example "sources in german",
- Notes: For example "notes in progress", or "notes in german",
- Media: For example "Picture belonging to Uncle Alfred".
Tags are available to use with all primary objects. Those objects can be tagged individually in their object dialog. In the category list view is possible to select also more than one object and tag them at the same time with Tag button, which opens Organize Tags dialog. You can add, edit, delete tags in this dialog. These affects in whole family tree. Also reordering of tags is possible.
Deleting wipes out every instance
Deleting a tag in Organize Tags dialog removes it from all objects, not just those selected in the view.
By adding a new tag or editing a tag, it is possible to define its color value and the text of the records it marks. In the list view of category, the rows are colored according the color of the uppermost tag of Organize Tags window.
