Topology

This repository contains the registry of OSG projects, site resources, and Virtual Organizations, as well as scripts for managing and displaying this information.

For registration instructions, please see this document.

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
• 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

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

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