This page serves to support GEO efforts in promoting GEO Members, Participating Organizations, and other data providers to register their data in GEOSS and provide it on-line.  The results of the Architecture Implementation Pilot - Phase 2 (AIP-2) can be used to promote a Best Practice for data deployment and data access.  See the Engineering Report and Video discussed below.

       

1.  AIP-2 End-to-End Discovery and Access: This topic is discussed in a full engineering report and an associated summary.  A scope and synopsis of the report follows:

Scope: This AIP-2 ER describes the practice of publishing, documenting, and registering contributed resources from the point of view of classes of GEOSS users who wish to discover and access those resources. It emphasizes two roles for the GEOSS Common Infrastructure: 1) Service-oriented structure for service-based application development by technically advanced users; and 2) Content-oriented search and linking for users with a less technical Web portal approach. "End-to-end" here refers to the connection between desired user discovery practices  and queries on the one end; and the provided resource interfaces and documentation on the other

Synopsis: The term ‘end-to-end discovery and access’ (E2EDA) describes the relationships between practices for publishing and providing earth observations, and the paradigms employed by GEOSS users for finding and getting to those observations. It comprises a variety of GEOSS practices:

·Providers choose to deploy resources (data, services, applications) based on earth observations.

·Providers then document and register those resources so they can be found and accessed.

·Consumers (users) pursue an objective and choose questions related to societal benefits and/or earth observations

·Consumers seek both relevant resources and the tools to work with them, such as client software.

These practices have to be connected if they are to be successful.:

·Users can only find resources that are described by the metadata and indexed by the properties that matter to them and with which they are familiar

·Earth observation information can only be utilized effectively when it is offered through services for which clients are readily available for access, comparative evaluation, and exploitation.

E2EDA emphasizes above all the need for clear communication of requirements across GEOSS between all stakeholders, so that each link in the discovery – access chain is both functional and essential.

     

    

2.  AIP-2 Demonstration Video: This video demonstrates data deployment.  The perspective is one of using the GEOSS Common Infrastructure (GCI) to deploy, test, register, and monitor a data access service.
