MTP: Core Technologies
This is a simple diagram to give you a sense of the core technologies underlying the Mark Twain Project.  As you can see, the primary components are the web site, the eXtensivel Text Framework, the Database and the Database Client.  Editors at the MTP (will) use the client to enter into the unified (most likely MySQL) database descriptive metadata about various works as well as any associated bibliographic, source, digital surrogate, or biographical material cross-referenced from the TEI texts of those works. That metadata about the objects will then be indexed and queried either as objects using services from the CDL Common Framework or with more direct lookups using Saxon SQL extensions – we’re not sure yet which, hence the dotted line. The TEI documents themselves will be handled by the CDL’s eXtensible Text Framework (XTF), a flexible indexing and query tool that supports searching across collections of heterogeneous data and presents results in a highly configurable manner.
