Minutes

  • JHU wrapping "package ingest extension" to POST bags to a given container in repo
    • Uses a streaming-oriented API (e.g. friendly to large chunked uploads, responds immediately with Server-sent events stream
    • JHU has use cases related to external tools generating bagged resources, transferring into repository for first time
  • Elliot Metsger refactored docker configuration of demo images to make it easier to specify alternate ports for API-X, other services
  • Christopher Johnson has been developing a suite of tools to support IIIF tools and workflows in Fedora, is using API-X in that suite
    • IIIF meeting in Vatican.  There is a subset of users that are interested in Fedora and/or API-X
  • Amherst moving to v1.1.0 of repository extension services, has improvements to triple indexing as named graphs
    • Best for API-X to wait for this release before integrating into docker images
  • Amherst triple indexer is more general then fcrepo for various reasons, not a drop-in replacement
    • Named graphs, not built around single-subject constraint
    • Does not filter by Indexable out of the box, but a user can add whatever filters they like
    • UMD was having heavy load on Fedora while indexing, may appreciate additional control
  • Action item:  Replace fcrepo-camel-toolbox indexer with Amherst indexer in demo Docker images
  • Want to remove as much internal logic from components (such as triple indexer as possible.
    • Leveraging API-X service binding to filter messages to async processes is compelling use case
    • NASA has multiple indexes, triplestores talking to triplestores, etc
    • API-X helps focus on data rather than technology/implementation details 
  • Issues wiith Modeshape slowness
  • Should put API-X on community calendar
