From some technical perspectives, I would suggest either repository or archive. Both of these words are very similar to each other and generally describe a place where things and/or data are stored. From a technical/computing standpoint, both have some more specific meanings beyond their normal definitions that focus specifically on data/information, which might make them more appealing to use for your purposes.
In computing, a repository is usually a common abbreviation for "data repository". If a programmer is creating a repository, then they are creating a data layer/interface for when other logical blocks of code that are doing a thing a user to access where the data is stored (a database, a file share, whatever).
An archive is a snapshot of a particular data store (again, database, file share, whatever) from a particular point in time and possibly a subset of data that is then stored long-term and not touched unless needed for some reason. Usually, those situations are when researching a current problem that may have been caused by something done in the past, or possibly to recover data that was lost in the live system.
"Archive" in particular also has some pop-culture references to describe a place where one goes to research a problem. For example, the Jedi Archives from Star Wars is described as a repository of knowledge.
Due to their technical meanings and pop-culture references, these terms could be appealing for branding a technical group meeting to share information with each other.
