This is a continuation of a discussion which took place in comments on this post.
- The area tags which originate from CoRR subject areas are named as
xxis the coresponding CoRR subject area codes and
descriptionis the descriptive name of the area. Examples are cr.crypto-security, cg.comp-geom, ds.algorithms and ds.data-structures. Note that some area tags deviate from the categorization in CoRR.
- The other area tags are labeled like usual tags. Examples are computability and quantum-computing.
There are two problems with the current area tags.
- Names depend on whether they originate from CoRR subject areas or not, which is not an important distinction. Therefore tags look simply inconsistent.
- There is no advantage of having the corresponding CoRR subject area codes in the tags. As I understand it, the only purpose of these codes is to indicate that they are area tags. However, this is incomplete because not every area tag has a two-letter code.
I think that a more consistent naming is better.
If the Stack Exchange server had a functionality of showing area tags in a different color, we would not have to distinguish them by names. Because it does not have such a functionality, it is better to distinguish area tags by names.
Therefore, I propose the following:
Proposal. Remove the
xx. part from the area tags of the form
xx.description and instead add a fixed prefix to all the area tags. As the fixed prefix, I suggest to use either
a. (for “area”) or just
.. [Edit: I removed the earlier suggestions
: because it turned out that a colon cannot be used in tags.]
