Thank you Kary and Mark for your input. The charter has been updated accordingly. I have removed the word "available" from "i)" since availability would be subject to Authentication and Authorization. Also "available" might be implying that DS should verify the information resource availability, which is not in scope of a DS responsibilities. Best Regards, Ali ESDS Charter: ESDS has been chartered to architect and define a protocol for Discovery Services. Discovery Services at its core offers to authenticated and authorized users the means to discover sources of information for a particular object. Discovery Services can be implemented as a decentralized directory of resources indexed by a shared identifier. The scope of Discovery Service is confined to only providing referral data to resource of information. Discovery Services need to be deployable in both closed networks as well as open and global networks such as Internet. ESDS will develop interfaces for users of Discovery Services as well as an interface for peer-to-peer communication among Discovery Services. ESDS will develop interfaces for: i) publishing the address of information resources [for a particular ID of an object of interest], ii) submitting one-time queries for retrieving the addresses of such resources, and iii) registering for standing queries, whose responses inform the client of addition, deletion or modification of DS records at a future time for a particular ID or group of IDs of an object or objects of interest. ESDS should support utilization of a trusted external identity management service for Authentication. ESDS should enable configuration of Authorization and Access Control for publishing clients to provide control over the reference data in Discovery Service. One of the applications motivating the development and standardization of Discovery Services is the increasing use of automatic identification technologies (in particular Radio Frequency Identification (RFID) ) to capture observations of tagged physical objects within the premises of a company and also as they pass from one company to another, in a supply chain or supply network. However, Discovery Services have a potentially wider generic applicability, as a bottom-up mechanism for constructing indices and referral systems for information about particular topics or keywords, particularly when the contributed information is distributed across multiple nodes on the internet and in particular, where the contributed information (and the metadata that enables its discovery) is not intended to be available to everyone or is not ordinarily discoverable by public web search engines that perform automated crawling and indexing of publicly accessible content.
