Introduction

XSEDE Information Services (XSEDE-IS) enable publishing and discovery of XSEDE federated infrastructure information. The XSEDE User Portal, science gateways, and other software components use XSEDE-IS web APIs to access infrastructure information presented to users, and to programmatically access infrastructure components.

XSEDE-IS contains static descriptive information aggregated from various information management systems, and dynamic status information collected automatically by monitoring and other information gathering tools. XSEDE-IS collects information from multiple sources and stores it in a central warehouse where it is cross-referenced and made available thru web APIs.

  1. XSEDE operated enterprise service descriptions and usage information
