Topics[edit]
PIDs and PID Manager[edit]
- configurable choice of PID System (instance) on a context level
- we do host several external institutions on single core service instance, also several solutions on single core service instance
- institutions may have different decisions on which PID system to use
- multiple PIDs allowed for object or version
- during ingestion, more or less at present PIDs are ingested as part of the metadata record
- this prevents some linking and searching, as different metadata schema have different metadata element names where they keep the identifier (and sometimes it is not clear if it is indeed a PID or is a local identifier)
- allowing for multiple PIDs where core services would be able to handle them indeed like PIDs (e.g. cross-check uniqueness in the repository)
- allowing to assign any of these multiple PIDs without creating a new item version
- allowing to assign any of these PIDs to any item version (not only to the latest version)
- maybe special object relation types could be solution to the last problem? in this case delivery with the item.xml would not be an issue
Outcome[edit]
- discuss it and create Colab page
Content model definition[edit]
- shall we try to identify issues which are not clear if they indeed depend on the cModel?
- should CModel contain structural and content specific behavior only or in addition it should contain settings for repository behavior and repository operations?
Outcome[edit]
- should be defined and discussed
- current CModel implementation is very simple
Read-only core services[edit]
- based on requirement for read-only PubMan
- interceptor for preventing modifications based on property value
- only system administrator would be allowed to make modifications in this case
- motivation: when some system actions are undertaken in which user are able to view, search and retrieve, but not able to make any modifications of data
PubMan Customizing[edit]
- CSS-Classes, Style files, etc.

- Improved and harmonized communication of eSciDoc
- eSciDoc Blog
- service names and classification
