The REST-based approach is another paradigm of SOA implementation, known as Resource Orientation Architecture (ROA), which follows the classical client/server model. It considers a service as a resource that can be accessed through the Web using traditional HTTP requests. These resources can be manipulated using the CRUD (Create, Read, Update, Delete) style via the typical HTTP methods, namely GET to request/retrieve a resource, POST to modify/update a resource, PUT to create a resource and DELETE to remove a resource. In the context of SURV-TRACK, the service provider or simply the server i.e. amobile robot or a sensor node) creates a resource for each service they provide and makes it accessible to service consumers or simply clients (i.e. control station) through a Uniform Resource Identifier... 

The I3C has specificied a Uniform Resource Name syntax and semantics for a life-sciences identifier. Submissions of proposed implementations of these technologies were also made to the Life Sciences Research Domain Task Force at the OMG. More information on the I3C specification can be found at http //www.i3c.org/wgr/ta/resources/lsid/docs/index.asp. 

URI Uniform resource indicator an identifier that uses the syntax defined in RFC 3986. URIs are divided into two parts bya colon. The first part is a label indicating the scheme of the URI, and the second part identifies the resource using the syntax appropriate to that scheme. For example, the URI tel +44-020-7... uses the tel scheme, which identifies telephone numbers there-... 

One flaw of this scheme is that identical documents served from multiple sites have different URLs. Also, URLs leading to the same document can become different if the server host has more than one name, or file system links are modifying the directory structure of the server. An alternative to the URL scheme called URN (uniform resource names ) is currently being discussed. A URN is an unique identifier of a document similar to an ISBN number, making copies and different versions of documents identifiable. The latest proposal in this area, backed by many scientific publishers, is the DOI (digital object identifier).
