20、 American National Standard is one in a series on the operation of informationand electronic products through remote and alternative interfaces and intelligentagents. The goal of this standard is to define an XML language for the description ofcompliant Targets and their Sockets, as used within the
21、URC framework for discov-ery purposes. A document conforming to this language is a Target Description.This document contains three annexes, which are informative and not consideredpart of the standard.Requests for interpretation, suggestions for improvement or addenda, or defect re-ports are welcome
22、. They should be sent to the InterNational Committee for Informa-tion Technology Standards (INCITS), ITI, 1250 Eye Street, NW, Suite 200,Washington, DC 20005.This standard was processed and approved for submittal to ANSI by INCITS. Com-mittee approval of this standard does not necessarily imply that
23、 all committee mem-bers voted for its approval.

It specifies a URI that indicates the content type that is used for the text content of the element. For example, when using the UNSPSC classification schema, the value h
27、ttp:/www.unspsc.org can be used. 7.10.8 The element may occur any number of times as a subelement of . It may contain (as subelements) preconditions on the use of the Socket, for example constraints on the users location in order to let the user control the Target. NOTE The element is defined as a p
28、laceholder in this standard, so that subsequent versions of this standard or Target vendors can add subelements to , possibly by using vocabularies from other standards. 7.10.9 Socket properties from DCMI Additionally any element and element refinement from the set of Dublin Core Metadata Initiative
29、 (DCMI) Metadata Terms may be used to describe a Socket, if appropriate. Each of them may occur multiple times within a element. In particular, the following DCMI terms may be applied to a Socket. specifying the product code (or instance code) of the Socket specifying the manufacturer of the Socket

The Resource Directory may contain references to subdirectories of resources (in the
33、 form of lower-level Resource Directories) on the Target, to Resource Sheets on the Target, to User Interface Implementation Descriptions (UIIDs) on the Target, and to external Resource Services. Annex B provides a sample Target Description with a complete Resource Directory, contained in the elemen
34、t of the TD. 7.12 Extensions for Security and Privacy For applications and environments where security and privacy mechanisms are implemented above the level of transport security, additional elements in the TD may be introduced for specific networking platforms and environments. For example, new su
35、belements of or may be specified in networking specific guidelines. However, these extensions should be kept as minimal as possible, to minimize the platform-dependence of the TD.

39、ular, the following DCMI terms may be applied: dc:identifier specifying the product code (or instance code) of the Target; dc:creator specifying the manufacturer of the Target; dc:publisher specifying the provider of the Target; dc:contributor specifying co-manufacturers of the Target.

Each of them may occur multiple times within a target element, except for the dcterms:modified element which, if present, shall only occur once. In particular, the following DCMI terms may be applied: dct
