This article provides an overview of work completed at Tsinghua University Library in which a metadata framework was developed to aid in the preservation of digital resources. The metadata framework is used for the creation of metadata to describe resources, and includes an encoding standard used to store metadata and resource structures in information systems. The author points out that the Tsinghua University Library metadata framework provides a successful digital preservation solution that may be an appropriate solution for other organizations as well.
Notes
Well laid out diagrams show the structural layers of resources; encoding exampes are included also.

Title
Towards a Digital Rights Expression Language Standard for Learning Technology
CA The Learning Technology Standards Committee (LTSC) of the Institute for Electrical and Electronic Engineers (IEEE) concentrated on making recommendations for standardizing a digital rights expression language (DREL) with the specific charge to (1) Investigate existing standards development efforts for DREL and digital rights. (2) Gather DREL requirements germane to the learning, education, and training industries. (3) Make recommendations as to how to proceed. (4) Feed requirements into ongoing DREL and digital rights standardization efforts, regardless of whether the LTSC decides to work with these efforts or embark on its own. This report represents the achievement of these goals in the form a of a white paper that can be used as reference for the LTSC, that reports on the current state of existing and proposed standardization efforts targeting digital rights expression languages and makes recommendations concerning future work.
Conclusions
RQ The recommendations of this report are: 1. Maintain appropriate liaisons between learning technology standards development organizations and those standards development organizations standardizing rights expression languages. The purpose of these liaisons is to continue to feed requirements into broader standardization efforts and to ensure that the voice of the learning, education and training community is heard. 2. Support the creation of application profiles or extensions of XrML and ODRL that include categories and vocabularies for roles common in educational and training settings. In the case of XrML, a name space for local context may be needed. (A name space is required for both XrML and ODRL for the ÔÇ£application profileÔÇØ or specifically the application ÔÇôLT application- extension) 3. Advocate the creation of a standard for expressing local policies in ways that can be mapped to rights expressions. This could be either through a data model or through the definition of an API or service. 4. Launch an initiative to identify models of rights enforcement in learning technology and to possibly abstract a common model for use by architecture and framework definition projects. 5. Further study the implications of patent claims, especially for educational and research purposes.
