OpenNode2 integrates Exchange Network Discovery Service (ENDS)
Just three months after the release of OpenNode2 comes an upgraded version - with some major new features like Exchange Network Discovery Service (ENDS) integration.
OpenNode2 is now capable of automatically registering an agency's Exchange Network (EN)presence and capabilities with the recently released national ENDS repository housed at EPA. ENDS is implemented as a set of services complying to the Exchange Network protocols - and the repository lets consumers of Network data discover which agencies have operational Nodes, and what data they are able to exchange via those Nodes.
The ENDS v1.3 exchange defines several Query services to retreive these lists of Nodes and services:
GetDataServices - returns ENDS_DataServices
GetSchemaList - returns ENDS_NetworkSchemaList
GetRequestList - returns ENDS_RequestList
GetStyleSheetList - returns ENDS_NetworkStyleSheetList
GetParametersList - returns ENDS_ParameterList
GetExampleList - returns ENDS_NodeExampleList
The six common data service payloads can be used to update data within the exchange just as they are used to consume data about the exchange. ENDS version 2.0 updated this approach to address issues raised by the EN community and align with OpenNode2.
With the release of OpenNode2 the Exchange Network has been gaining momentum - and the ENDS repository may become an essential tool to ensure that the community is aware of the Network's ongoing expansion.
