Purpose of RCS• Catalog or Registry of IT components, services and tools
of interest to EPA, Exchange Network partners, States, Tribes, developers, and others
• Provides a single interface by which users can search for existing IT assets
• Leverages and maximizes investments by reducing redundant development
• Includes asset types such as XML schema, widget tools, Web services, software tools, databases, programming code, data models, and others.
• Systems and applications that take advantage of RCS can be developed more quickly, at a higher quality, and at a lower cost
• Adds meaning and value by showing relationships among assets and classifying them in taxonomies
• Goal is to become the agency hub for applications, services and data

Principles
• No redundant registration or entry
• Owner decides level of sharing
• Many metadata attributes, few mandatory
• Registration in any phase of the development life cycle
• Re-use may occur at many levels, including:– Full re-use– Modification of existing asset– Ideas, Best practices, lessons learned

Systems, models• Automatic harvesting from the Environmental Dataset Gateway
(EDG) - datasets• Automatic harvesting from the Exchange Network Discovery
Service (ENDS) and the Exchange Network website – Dataflows and web services
• Future automatic harvesting from DERS (Data Element Data Registry) – Data Dictionaries, Code Sets
• Future interface with tool for Agency Canonical Model• Future interface with Schema workbench for easier dataflow
creation

Current Activities• Reaching out to EPA Program Offices and Regional
Offices, States and other partners• New asset types, including mobile apps, linked datasets.• Working with Program Offices and OARM to work RCS into
contract language• Looking to make RCS part of CPIC and ADC process• Establishing governance, workflow and quality processes• Demonstrating new easier, faster and more powerful
search interface• Showing RCS widget in Developers Dashboard and other
agency web pages• Starting to explore federation or connections with other
