IVOA Operations Interest Group Charter
Goal of the IVOA Operations Interest Group
Coordinate and publicize activities of individuals, institutions and groups interested in facilitating robust operations of distributed astronomy applications, particularly those based upon implementations of IVOA protocols.
Specific responsibilities
- Publicize existing forums and encourage new ones for monitoring services, notifications, discussions and questions regarding “real-time” operations of VO / distributed services.
- Promote discussion within the IVOA on standards and practices that would increase the reliability of VO implementations.
- Develop nominal implementation strategies for VO services as guides to best practice in the operational use of VO protocols.
- Periodically provide reports to the IVOA executive and WGs summarizing availability, quality and usage statistics for distributed services and VO protocols.
- During the IVOA standards review process, assess the validation capabilities that are now required as part of new standards.

Operations Projects
Procedure for Removing Non-Responsive Services
VO-Paris has presented a
plan for a process for removing non-responsive services from the Registry which was presented to the Exec and discussed in the Interest Group. A revised version will be provided.
A revised procedure was adoped by the IVOA in October 2016.
Coordination of VO validation services
It was agreed that the three sites that are currently collecting validation statistics will try to coordinate their activities. The first step is to provide a standard set of identifiers for issues so that results from the validators can be compared. This will allow us to compare the validator results and 'validate' the validators.
NCSA/HEASARC Validation tests (Conesearch and SIA)
VO Paris Validation Test
ESA Validation Tests
Data from these documents has been combined into the following documents:
Analysis of the results from these documents suggests that the validators are making somewhat different queries and that any given validator is only testing a subset of all poassible errors. Negative results regarding a service are generally valid. In principle a service should pass all validators.
