Under the "Managed metadata" section of the SharePoint limitations page the following is currently written: "1 million total terms, having a total of 2 million term labels and 1 million term properties (these limits are for global & site-level terms combined). 1,000 global term sets and 1,000 global groups." What I however do not clearly understand are these questions:
How many local term sets and local term set groups are allowed, i.e. term sets that are only applicable to a specific site collection (in the text above it only mentions the limitations on the global term sets)?
If you reuse/pin a term in different term sets, are they considered as multiple terms or just one term?
You can have 1 million terms but 2 million term labels. Are term labels here the same as "Other labels", so in average a term can have one additional "Other label"?
