Catalog Services for Portal - PoC

  • standalone prototype Geonetwork replacement written in Haskell!
  • implements facet search, facet counts, freetext search, pagination, online resources, usage limits, attr constraints etc to drive AODN Portal
  • csw harvesting of external catalogues
  • support for mcp2.0/19139, but not dependent on metadata form - subset only, simple to manage, transform, extend
  • freetext search built on top of postgres 9.5 freetext support
  • iso19139 records, skos vocabulary/concepts relationally modelled. localized to db backend, supports easy cloud hosting
  • logos stored and served from the db.

psql -h postgres.localnet -U admin -d postgres -f sql/db.sql
psql -h postgres.localnet -U harvest -d harvest -f sql/tables.sql
psql -h postgres.localnet -U harvest -d harvest -f sql/views.sql
