The ARC Hierarchical Endpoints Registry (ARCHERY) is a novel DNS-based service endpoint registry for e-Science infrastructures.

ARCHERY implements a minimalistic data model representing services and their endpoints within e-Infrastructures and embeds the service endpoint information directly into the DNS database.

ARCHERY inherits all the benefits of the DNS infrastructure since deployment, management and operation of the system is fully relying on the DNS protocol.

All the services available within an e-Infrastructure are indexed by means of an ARCHERY instance.

Nordugrid Collaboration, the organization behind the ARC software, operates a top-level ARCHERY hosted within nordugrid.org DNS zone.

Similar hierarchical service catalogues can be deployed by any organization or project under a dedicated DNS zone. Instructions for howto create such registry is given here.

Note

Sites are NOT required to run any reristration service on an ARC6 CE.

Read this document to understand what needs to be done so that an ARC6 CE would appear in an ARCHERY registry.

Previously a different technology was used as a service registry that was based on LDAP (see details here).

Following documents cover the generic aspects of the ARCHERY deployment and operation, including the very specific case of NorduGrid infrastructure:
