Metacat

separate the class and the ontology from the the URI for easier reading. putting them in a table also helps

include links from annotation to the data package metadata

include stylesheet to display annotation document on it's own (in addition to within a resultset)

include the column name that the measurement is mapped to

list the currently registered ontologies (in case someone wants to unregister them?)

rearrange the ontology registration page - bioportal-hosted ontologies come first

include dropdown of all bioportal ontologies - you can choose to register or unregister them with metacat for annotation-based searching. perhaps not the most elegant workflow, but better than having to manually collect the URIs and URLs.

include annotation display in the search results - NOTE using XPath 2.0 function for accessing the ontology URIs that are included as namespaces in the annotation. adding Saxon jar for this.

include a page for [un]registering ontologies with the ontology manager in the semtools plugin

basic query can be issued and includes:
-match any/all
-from same observation
-for Entity, Characteristic, Standard, Protocol, Measurement
