Wiki page: https://wiki.oasis-open.org/regrep/documents/plan/regrep4/RepositorySPI

• Farrukh reviewed the proposal
  
• Reagan described EarthCube Brokering Concept Award NSF sponsored project
  
• Reagan has offered to approach EarthCube Brokering Concept Award group to see if they are interested in exploring a proposal based on RegRep 4 and Repository SPI
• Use Cases
• Nikola: asked about File Systems repository. Companies like Google and Microsoft are trying to make file systems search-able
• Farrukh: Repository SPI should support file system repository with keywords search capability. Current proposal supports this use case.
  
• Carl: How does RegRep 4 spatial extensions relate to this proposal
• Farrukh: the two are complimentary and orthogonal
  
• Carl: What about cyber security issues?
• Nikola, Carl: We need to liaison with other TCs and learn more about relevant standards. Examples include OASIS Clouds Authorization TC, OAUTH,
• Requirements
• Query is key requirement
  
• Reagan: ability to do an arbitrary operation with arbitrary parameters is a must
• Ability to list objects is a key requirement. This can be a special case of arbitrary operation with arbitrary parameters
• Leverage existing standards
• Reagan: we use posix compliant interface in iRODS
  
• Farrukh: Posix does not give query capability
• Reagan: Most repository do not support query and therefor it should be optional in Repository SPI
  
• Nikola: Is OASIS CMIS a candidate for Repository SPI
  
• Carl: CMIS approach was to reflect best practice on how you store text in a relational database and querying using SQL
• Farrukh: CMIS is not a good fit because it uses SQL subset for query language. How to map subset SQL to specific query languages like SPARQL and XQuery?
• Nikola: Agree CMIS is not feasible. Need to be agnostic as possible with query language
• Farrukh: What standards are being considered by EarthCube Brokering Concept Award
• Reagan: OpenDAP is one but it is only NetCDF specific, focused on specific data formats
• Carl: lets stick with our parametrized queries but extend to support additional canonical parameters and queries to support repository operations like "list objects" etc.
• Nikola: What about ISO 14721 
• Reagan: Did not think it was a good fit (scribe cannot recall reasons)
  
  
• Meeting adjourned with general consensus on value of Repository SPI and to continue building on current proposal in subsequent meeting
