Metadata sub-meeting (at MathDL meeting), 3/17/01:

3 levels of classification for mathematics taxonomies:
  1. AMS: professional, serious undergraduate mathematics; good for definition of content categories
  2. Level 2: high school and college, 9 – 14
  3. Level 1: school math, k – 8

Unify 2 and 3

Discussion of IEEE (will be adopted by IMS and ADL):

metadata categories and the needs of the various Mathematics digital libraries

In summary, there are few extensions to the newest IEEE model, working version 6, that we agreed on in the metadata meetings. As an aside, history indicates that the IEEE model will be the basis, if not wholly adopted, as the newest IMS LOM and incorporated into ADL’S SCORM document.

The numbering scheme in the following notes are references to the IEEE model. Items highlighted in red are recommended extensions to the IEEE metadata standards. Our agreement was that these extensions will be adopted by the Mathematics digital libraries (represented by this group) and we recommend their adoption by the entire NSDL initiative. Other notes are comments and/or discussion items.

Recommend source be identified as LOMDL

    1. adopt guid when is adopted by IEEE and IMS, global unique identifier; not used now
    2. through 1.6: nothing to add
    1. adopt IMS sanction that do not use keywords when can describe with other metadata
    2. nothing to add at this point
    3. nothing to add

2.1 version: Should we have a universal versioning system adopted when IMS adopts the guid? Should we have a versioning system that is shared throughout nsdl? Should we use this element to describe the author’s versioning system?

How do we handle the ripple effect of granular objects having a version change?

2.2 no additions

2.3 no additions

section 3 implies registry of metadata

4.2 size: the size of what it would take to download (in bytes) in an uncompressed manner

4.4.1 We recommend five types: operating system, browser, hardware, plug-in, and software

      1. Name: plug-ins – open; Software – mathematica, maple, matlab, mathcad, derive, maxima, spss, sas, splus, minitab, jumpin, sysstat, reduce, geometer sketchpad, cabri, msoffice, LaTex, other; hardware – open

Section 5

    1. Extend vocabulary to include lab, project, lesson, lesson plan, presentation, equation, example, demonstration, video, manipulative, assessment

Sections 6 – 9 No additions
