Relationship between VOs and Sites

Oct 13, 2025 by magicalceylontours.com 81 views

In this article, we will discuss the list of available queries and potential modifications. The queries are categorized into three main sections: VOs, Sites, and the relationship between VOs and Sites.

VOs

Query 1: List of All Existing VOs

The first query is to retrieve the list of all existing VOs. This can be achieved by visiting the following URL: https://is.ops.fedcloud.eu/vos/. This query is already implemented and provides a comprehensive list of all existing VOs.

Query 2: List of Sites Supporting a VO

The second query is to retrieve the list of sites supporting a given VO. This can be achieved by visiting the following URL: https://is.ops.fedcloud.eu/sites/?vo_name=<example>. However, there is a note that suggests this URL might be modified to https://is.ops.fedcloud.eu/vo/<example> instead.

Query 3: List of VMIs Available for a VO

The third query is to retrieve the list of VMIs available for a given VO. Unfortunately, this query is currently missing and needs to be implemented.

Sites

Query 4: List of All Existing Sites

The fourth query is to retrieve the list of all existing sites. This can be achieved by visiting the following URL: https://is.ops.fedcloud.eu/sites/. This query is already implemented and provides a comprehensive list of all existing sites.

Query 5: List of Supported VOs/Project IDs for a Site

The fifth query is to retrieve the list of all the supported VOs/project IDs for a given site. This can be achieved by visiting the following URL: https://is.ops.fedcloud.eu/site/12355G0/projects. However, there is a note that suggests this query might be modified to use the site_name instead of the site_id.

Query 6: Details of a Site

The sixth query is to retrieve all details about a given site. This can be achieved by visiting the following URL: https://is.ops.fedcloud.eu/site/?site_name=IISAS-FedCloud. Alternatively, the same information can be retrieved by visiting https://is.ops.fedcloud.eu/site/12355G0/. However, there is a note that the <site_name> parameter in https://is.ops.fedcloud.eu/site/?site_name=<example> must be required and it is optional at the moment, returning a 404 if empty.

Relationship between VOs and Sites

Query 7: List of VMIs Available for a <VO, Site>

The seventh query is to retrieve the list of VMIs available for a given <VO, site>. This can be achieved by visiting the following URL: https://is.ops.fedcloud.eu/site/12355G0/vo.usegalaxy.eu/images. However, there is a note that in principle, the list of available VMIs should be queried at VO-level only; However, it may be nice to have this available as a sanity check.

Query 8: List of VOs/Project IDs for a <VO, Site>

The eighth query is to retrieve the list of VOs/project IDs for a given <VO, site>. This can be achieved by visiting the following URL: https://is.ops.fedcloud.eu/site/12355G0/vo.usegalaxy.eu/project. However, there is a note that this query might not be very interesting to make.

Conclusion

In conclusion, the available queries provide a comprehensive list of information about VOs, Sites, and the relationship between them. However, there are some queries that are currently missing or need to be modified. By implementing these queries, we can provide a more comprehensive and user-friendly interface for users to retrieve the information they need.

Future Work

In the future, we can consider implementing the missing queries and modifying the existing ones to make them more user-friendly. We can also consider adding more features to the interface to make it more comprehensive and user-friendly.

Recommendations

Based on the available queries, we recommend the following:

Implement the missing queries (Query 3 and Query 7).
Modify the existing queries to make them more user-friendly (Query 2 and Query 5).
Consider adding more features to the interface to make it more comprehensive and user-friendly.

In this article, we will answer some frequently asked questions about the available queries and provide more information about the queries discussed in the previous article.

Q: What are the available queries?

A: The available queries are categorized into three main sections: VOs, Sites, and the relationship between VOs and Sites. The queries are:

VOs: Query 1 (List of all existing VOs), Query 2 (List of sites supporting a VO), and Query 3 (List of VMIs available for a VO)
Sites: Query 4 (List of all existing sites), Query 5 (List of supported VOs/project IDs for a site), and Query 6 (Details of a site)
Relationship between VOs and Sites: Query 7 (List of VMIs available for a <VO, site>) and Query 8 (List of VOs/project IDs for a <VO, site>)

Q: What is the purpose of each query?

A: Each query serves a specific purpose:

Query 1: Provides a comprehensive list of all existing VOs.
Query 2: Allows users to retrieve the list of sites supporting a given VO.
Query 3: Currently missing, but will provide the list of VMIs available for a given VO.
Query 4: Provides a comprehensive list of all existing sites.
Query 5: Allows users to retrieve the list of supported VOs/project IDs for a given site.
Query 6: Provides all details about a given site.
Query 7: Allows users to retrieve the list of VMIs available for a given <VO, site>.
Query 8: Allows users to retrieve the list of VOs/project IDs for a given <VO, site>.

Q: How do I use the queries?

A: To use the queries, simply visit the corresponding URL:

Query 1: https://is.ops.fedcloud.eu/vos/
Query 2: https://is.ops.fedcloud.eu/sites/?vo_name=<example>
Query 3: Currently missing
Query 4: https://is.ops.fedcloud.eu/sites/
Query 5: https://is.ops.fedcloud.eu/site/12355G0/projects
Query 6: https://is.ops.fedcloud.eu/site/?site_name=IISAS-FedCloud

Query 8: https://is.ops.fedcloud.eu/site/12355G0/vo.usegalaxy.eu/project

Q: What are the notes and recommendations for each query?

A: The notes and recommendations for each query are:

Query 2: The URL might be modified to https://is.ops.fedcloud.eu/vo/<example> instead.
Query 5: The query might be modified to use the site_name instead of the site_id.
Query 6: The <site_name> parameter in https://is.ops.fedcloud.eu/site/?site_name=<example> must be required and it is optional at the moment, returning a 404 if empty.
Query 7: In principle, the list of available VMIs should be queried at VO-level only; However, it may be nice to have this available as a sanity check.
Query 8: This query might not be very interesting to make.

Q: What is the future work for the queries?

A: The future work for the queries includes:

Implementing the missing queries (Query 3 and Query 7).
Modifying the existing queries to make them more user-friendly (Query 2 and Query 5).
Considering adding more features to the interface to make it more comprehensive and user-friendly.

Q: What are the recommendations for the queries?
