Metacat

Add xpointer FragmentSelectors to each annotation.
Split attribute label into tokens to attempt matching to OBOE concepts.

include code to generate random annotations for UI testing. Effective, but can be confusing to see so many unrelated concepts on duplicate EML packages.

include characteristic_sm field with SPARQL query

include SSLVerify* directives for client certificates and a pointer for getting the DataONE chain files.

Added an explanation of "metacat context" to the Metacat Themes docs based on questions asked by an actual user following our instructions in the docs.

Edited the docs to incude more details about creating a custom theme

Remove the code to lookup alias dn in the getGroups method.

Rather than directly to modify the env, we use context.addToEnv.
This fixed a bug in non-tls env, the alias log-in doesn't work.

first pass at generating annotations from EML attribute information. uses the OpenAnnotation model that the metacat-index tests assume which allows us to populate dynamic index fields for the annotation class[es]. There is still much to be done with finding appropriate concepts for each attribute. https://projects.ecoinformatics.org/ecoinfo/issues/6256

switch to index standard since it is more likely we will be able to determine this from our existing EML attribute information. https://projects.ecoinformatics.org/ecoinfo/issues/6253
