new properties for OU[edit]


  • questions on searching for predecessors/successors
    • items should not be indexed with info on pred/succ
    • when a search for all items of an OU and all of its predecessors is run:
      • pass 1 (by client): give all predecessors of an OU
      • pass2 (by client): give all items with OUs in (OU, OU predecessors)
  • questions on parent/child
    • if structure is changed path in item index will be only changed if the item is changed

OAI-PMH Provider and DC Transformation[edit]


  • check possibility in 1.2
    • transformation works for single metadata record
    • offered as a resource
    • given to content model
  • Core service URL will not bein OAI-PMH identifier
    • core-service URL contain internal identifier

Mime Types and management[edit]

  • consequences in PubMan - differences between CoNE, core-service list, IANA
    • immediate steps: CoNE MimeTypes will be synchronized with core-service list mime types if possible
    • organizational: who will be responsible? (CoNE to be public source, fetched from core-service on regular basis? - core service MIME-updates etc.)


  • single list -> maintained by MPDl
    • content models may have restrictions, but independently on CoNE
    • CoNE can be used only for data entry

Status of Heap Space Problem in Pubman Production environment[edit]

  • Solved?


  • problem was in application logic, delivers a lot of results
  • another problem has opened which was the initial cause e.g. searching for

"escidoc.publication.object-type='item' AND escidoc.publication.subject=\& and escidoc.publication.content-model.objid=X " actually cuts the query completely after "\&" and it makes a query on escidoc.publication.object-type='item'

migration to coreservice 1.2[edit]

  • Status (?) - potentially from MPDL

Core-service 1.3[edit]


  • eSciDoc-Colab Page setup
  • Alignment of tools and processes (e.g., Maven)
  • Improved and harmonized communication of eSciDoc
  • eSciDoc Blog
  • service names and classification
  • documentation of services
  • installation guides
  • eSciDoc Lab: Colab page gathering experimental modules
  • Exchange of staff members for specific developments or share development
