XML Registry


Welcome to the interim XML Registry for the Environmental Information Exchange Network. This Registry provides the capability to share information about XML Data Exchange Template (DETs), XML Schemas, Namespaces, WSDL files, and other supporting files needed to map data flows between partners. The Registry contains information about schemas approved for use on the Network, as well as information about schemas under development. The XML Registry provides a clearinghouse for information related to data flows on the Network.

Data Submission

Registration of new schema information in the interim XML Registry can be done using a Microsoft Excel spreadsheet data template. Below is the draft data input template and an example template populated with OWWQX schema data.

To submit new information please contact: Nathan Wilkes via email at wilkes.nathan@epamail.epa.gov or by phone at 202-566-0335.

XML Object Search can access all information in two ways:

  1. To search for a specific word or phrase, enter text (e.g., water) or a text string (e.g., Water Quality) in the keyword field. The search will query all XML object types, unless a specific XML object type (e.g., XML Schema) or XML object stability (e.g., Static) is selected from the pull-down lists. The keyword portion of the XML object search queries all text fields (e.g., name, acronym, abstract, etc.).
  2. To obtain a complete list of XML Objects by type (e.g., XML Schema) or stability (e.g., Static), select a type from one of the pull-down lists and leave the keyword field blank.
