Q:

Is it possible to download the SO Tags database?

Is there a way for me to download the full list of tags (and synonyms) used on Stack Overflow?
My intent is to import these tags into an SQLite database as part of a process to convert all of my delicious bookmarks and tags to the ones used here on Stack Overflow. 

A:

As of right now, you can only get a list of tags. Tag synonyms are not publicly available yet, but have already been requested.
There are a few ways of going about getting the data:

Download the latest Data Dump, and use an XML parser to extract the tag information
Use the Data Explorer (a public-facing data dump loaded into SQL Server) and one of the techniques described in my answer here.
