The eXtensible Resource Allocation Service (XRAS) is our platform for managing proposal review and resource allocation processes and is the primary development effort under ACCESS Allocations. We also offer XRAS as a hosted service to other organizations to support their separately managed allocation processes.

For more information on using XRAS to support your allocation management needs, contact allocations@access-ci.org. 


XRAS provides interfaces and components to support the submission, review, and administration of allocation requests. With its extensive customization features, XRAS can support a wide variety of policy and procedure requirements. The review component supports multiple review phases, enforces conflicts of interest, and allows allocation panel members to view requests, download documents, and enter their reviews. The administrative system provides panel management, tools for meeting logistics and review assignments, email notification capabilities, award entry and processing functions, and reporting capabilities.

Sites with lightweight allocation procedures can choose not to use the review and panel management features, instead focusing on using XRAS for allocation tracking and basic administration.

Site Requirements

To use XRAS, your site needs to meet only minimal technical requirements. Primarily, the resources to be allocated by your site registered in the ACCESS Cyberinfrastructure Description Repository (CIDeR). XRAS supports optional integration with your local identity management and authentication system and your local resource accounting system; XRAS clients also have the option of developing custom submission user interfaces, tailored to their needs and embedded with their organization's web or portal sites.

ORCID for Resource Integration

XRAS is an ORCID Certified Service Provider. XRAS lets ORCID member institutions post information about allocated projects to your researchers’ ORCID profiles via integration with ORCID for Research Resources.
