We are mainly interested in a current effort to develop a [http://www.phylo.org/treebase_pdf_docs new schema for TreeBase II] (these are images of the schema; Arlin has UML and XMI versions from the developers that he can share within the evoinfo group).
 
 
 
# The specification language is SQL
 
# The scope covers character data, trees, and some analysis information; essentially it is a large subset of what is covered in a NEXUS file
 
# Within this scope, the schema has similar limitations to NEXUS (poor support for specifying models and complex data sets)
 
# Development is controlled by the administrators
 
# We are not aware of a versioning policy.
 
# We are not aware of a conformance policy.  The administrators are loose about the NEXUS format for uploading data to TreeBase.  In the past they have corrected invalid files received from users.
 
# TreeBase is actively used and we expect that the TreeBase II update will take place eventually
 
# TreeBase is widely used for archiving in some areas of the systematics community.  It has not been widely used for meta-analyses, to our knowledge.  Currently the interface is very limited.
