Is there a hard limit to the number of tags that can be associated with an item? The number of tags in a group? In a database? Any limit to the hierarchical nesting of tags? If it makes a difference I’m running DEVONthink 3.6.1 on macOS 10.15 and 11.1, that’s Catalina and Big Sur for those of us who prefer words.
Why? I’m using DEVONthink for genealogy and family history and rely heavily on tags in my workflow. There are 3 distinct aspects of traditional genealogy: research, analysis, and reporting. As each item is discovered during research, I import (or if impractical, index) it into a database and tag it with the exact data found in the item. For example, a person’s name, “Marie” is tagged exactly as “Marie”, not “Maria”, or “Mary”; a place, “Phily” would be tagged “Phily” not “Philly” or “Philadelphia” even though I may “know” one of the others is “correct”. During analysis, I can use DEVONthink’s excellent tools to classify items, find similarities between/among them, and show connections. And yes, during analysis, I add more tags, effectively mapping/associating the raw data from the research phase with the conclusions of my analysis, in the above examples, perhaps, ‘Mary’ and ‘Philadelphia’.
I would expect at some point I might see a performance issue, and that would be acceptable. In practice, so far, I’ve reached up to over 100 tags per item and over 20K tags per database without any issues whatsoever. If there is/are hard limits I could always create a subset of my data by geographic region or time period as a workaround, however it would be preferable to keep an entire project together in a single database.
Thanks in advance for any assistance!
