11、reproduction or networking permitted without license from IHS -,-,- IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development
12、process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process a
13、nd establishes rules to promote fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injur
14、y, property or other damage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance upon this, or any other IEEE Standard document. The IEEE does not warrant or represent the accuracy or content
15、of the material contained herein, and expressly disclaims any express or implied warranty, including any implied warranty of merchantability or fitness for a specific purpose, or that the use of the material contained herein is free from patent infringement. IEEE Standards documents are supplied “AS
16、 IS.” The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subjec
17、t to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is
18、reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. In publishing and making this document available, the IEEE is not suggesting o
19、r rendering professional or other services for, or on behalf of, any person or entity. Nor is the IEEE undertaking to perform any duty owed by any other person or entity to another. Any person utilizing this, and any other IEEE Standards document, should rely upon the advice of a competent professio
20、nal in determining the exercise of reasonable care in any given circumstances. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institut
21、e will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standa
22、rds Coordinating Committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shal
23、l make it clear that his or her views should be considered the personal views of that individual rather than the formal position, explanation, or interpretation of the IEEE. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE.
24、 Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE-SA Standards Board 445 Hoes Lane Piscataway, NJ 08854 USA Authorizat

28、rt of IEEE Std 1484.4-2007, IEEE Trial-Use Recommended Practice for Digital Rights Expression Languages (DRELs) Suitable for eLearning Technologies. The Digital Rights Expression Languages Working Group (DRELs WG) of the IEEE LTSC was formally established in March 2003 at the Paris quarterly meeting
29、 of the LTSC and was initially co-chaired by Juliette Adams. This followed a series of study group meetings held throughout 2002 that investigated both DRELs and Digital Rights Management (DRM) in relation to the needs of learning, education, and training. With a view to constraining the problem spa
30、ce and minimizing stakeholder confusion, the WG developed a project proposal that focused only on DRELs. The resulting Project Authorization Request (PAR) was accepted on 14 April 2003. During the agreed work program, it became clear that the need for DRELs within education and training communities
31、worldwide is still at an embryonic stage. However, while the sector has voiced its strong need for DRELs, it has not, as yet, identified unique requirements that current DRELs cannot satisfy. This reflects the state-of-play within the eLearning industry where learning technologies associated with pe
32、dagogy, process, and learning activities are still largely in the research and development phase. This does not mean that such requirements may not exist, but they have not been explicitly identified in this trial use recommended practice. The working group gathered a series of use cases that were s
33、ubmitted following the initial call for contributions issued on 2 June 2003. These use cases are detailed in Annex A. Most use cases were provided by stakeholders who have not yet implemented DRM systems but who are keen to make use of them. From these use cases, the WG then extracted a number of re
34、quirements, which are included in the normative section of this document (see Clause 2). In order to align these requirements with existing rights expression languages, the WG received three language mappings, including MPEG REL, formally known as ISO/IEC 21000-5:2004; the open eBook Forum (OeBF) pr
35、ofile of MPEG REL; and, Open Digital Rights Language (ODRL) (see Annex A, Annex B, and Annex C). Based on these mappings and reviews thereof, the working group produced a table summarizing which requirements are met by each language mapping. This trial-use recommended practice aims to provide a basi
36、s from which stakeholders within learning, education, and training can make informed decisions about their DREL needs.

All rights reserved. Patents Attention is called to the possibility that implementation of this recommended pr
39、actice may require use of subject matter covered by patent rights. By publication of this recommended practice, no position is taken with respect to the existence or validity of any patent rights in connection therewith. The IEEE shall not be responsible for identifying patents or patent application
40、s for which a license may be required to implement an IEEE standard or for conducting inquiries into the legal validity or scope of those patents that are brought to its attention. Publication of this trial-use recommended practice for comment and criticism has been approved by the Institute of Elec
41、trical and Electronics Engineers. Trial-use standards are effective for 24 months from the date of publication. Comments for revision will be accepted for 18 months after publication. Suggestions for revision should be directed to the Secretary, IEEE-SA Standards Board, 445 Hoes Lane, P.O. Box 1331,
42、 Piscataway, NJ 08855-1331, and should be received no later than 22 February 2009. It is expected that following the 24-month period, this trial-use standard, revised as necessary, shall be submitted to the IEEE-SA Standards Board for approval as a full-use standard.

43、andard was completed, the working group had the following membership: Magda Mourad, Chair John Mason, Technical Editor Juliette Adams (Initial co-Chair) Leah Berkhoff Stephen Downes Rachel Ellaway Kameshwar V.
