Content: Overview of DAL types of data, DTThe concept of the class hierarchy of DAL services agreed to in Cambridge was briefly reviewed. See slide 10 in the WG summary presentation.SIA V1.1, DAL service infrastructure; key issues, DTA number of active issues required for SIA V1.1 were discussed. See slides 11-20 in the WG summary presentation.The issues discussed included:
A: Within authority ID domain data IDs assigned by each authority. One 'can' state that a ID is a replica, but this is not ensured. Q: How to state data quality? A1: Part of data model and characterization of data. A2: Resource metadata allows have basic quality description of data collection. Q: What about IDs of OTF processed products? A: Goes to deeper question of what does it mean to publish data to the VO? IDs do not change, but data may go away. Proposed evolutions for SIA, Francois BonnarelA proposal was made to add support to SIA for templating the access reference URL.
