Topology

This repository contains the registry of OSG projects, site resources, and Virtual Organizations, as well as scripts for managing and displaying this information. The information was sourced from the former OIM site that was hosted at oim.grid.iu.edu. This README contains the following sections:

• Structure of the Registry
• How to Register
• Viewing the Registry
• Getting Help

Structure of the Registry

The data is organized as files in YAML format as follows:

• projects/ contains information about research projects that run jobs on OSG. Each project has its own file, named <PROJECT>.yaml

• virtual-organizations/ contains information about Virtual Organizations (VOs). Each VO has its own file, named <VO>.yaml. Additionally, each VO has a file that contains information about WLCG metric reporting groups called REPORTING_GROUPS.yaml.

• topology/ contains information about the topology of the resources that OSG sites provide. Resources such as HTCondor-CE, GridFTP, XRootD, or Squid are collected into "resource groups." Each resource group has its own file, which are further organized by facility, and then by site. Resource group files are named <FACILITY>/<SITE>/<RESOURCEGROUP>.yaml

  For example, the OSG resources in the Center for High Throughput Computing can be found in the following file: topology/University of Wisconsin/CHTC/CHTC.yaml

How to Register

The formatting of the YAML files for the different types of registration data are described in the following template files:

The following data...	Is defined by template file...	And should be copied to location, relative to the Git root directory...
Project	template-project.yaml	projects/<PROJECT NAME>.yaml
Resource Downtime	template-downtime.yaml	topology/<FACILITY>/<SITE>/<RESOURCE GROUP NAME>_downtime.yaml
Resource Topology	template-resourcegroup.yaml	topology/<FACILITY>/<SITE>/<RESOURCE GROUP NAME>.yaml
Virtual Organization	template-virtual-organization.yaml	virtual-organizations/<VO NAME>.yaml

The comments in the template files explain the structure and the meaning of the data.

Note: File and directory names must match the name of your project, VO, facility, site, or resource group, as appropriate. This includes case and spaces.

New registrations

To create a new resource group, project, or VO, please create the YAML file according to the table above, and use the corresponding template file to fill in the appropriate information. If you do not feel comfortable creating the new file yourself, send an email to [email protected] with details about your resource group, project, or VO.

Updating existing registrations

To update the data for your site resources, project, or VO, make and submit your changes using one of the following methods:

• Modify the corresponding YAML file and submit your changes as a GitHub pull request.
• Send an email to [email protected] requesting your desired changes.

For definitions for the various fields, consult the corresponding template file for the type of data you are updating.

Viewing the Registry

Registry data can be accessed in two formats: the YAML files can be accessed directly through the GitHub interface or from a clone of the GitHub repository. Alternatively, the registry data can be accessed in XML format at the following URLs:

The following data...	Can be accessed in XML format via URL...
Project	https://my.opensciencegrid.org/miscproject/xml
Resource Downtime	https://my.opensciencegrid.org/rgdowntime/xml
Resource Topology	https://my.opensciencegrid.org/rgsummary/xml
Virtual Organization	https://my.opensciencegrid.org/vosummary/xml

These XML pages are compatible with the XML format once provided by myosg.grid.iu.edu.
