Extending the LOM

Yes - seems possible to extend the LOM to create new elements - but also keeping some 'standard' metadata.

Possible problem with Word XML

Annoyingly I have noticed that Word repeats parent element tags when you mark up - even elements that should be declared once.

This is annoying as it breaks the element tree - but both Word and HIVE seem to validated it fine!!!

Oh well - may be something to repair here!!

Will investigated.

Similiar Project Reflections

See: http://metadata.cetis.ac.uk/usage_survey/cs_hlsi.pdf

"Use is made of granularity (vocabulary is {object, page, document} ) although this information is not stored in the IMS metadata record. The materials are stored in folder systems to represent the hierarchy. i.e. document folders contain pages and pages contain objects."

An interesting comment - may be worth looking into doing this for this project - as we have the option - see image.



Their specific reflections (I have experienced some of this too)

"Several versions of the IMS specification were looked at during the course of the project. Some problems with the specification were:

Examples
The examples given for how to use the elements were unclear,
particularly in the earlier documentation.

Best Practice Guidelines
There were not enough best practice guidelines.

Unclear Explanations
The catalog entry field caused some confusion initially. It was unclear if catalog and catalog entries were to be used for external searching.

New Versions
The IMS specification changed several times during the course of the project. It is quite difficult to automate the processes of upgrading and downgrading, particularly when vocabularies changed and when the specification changed to allow more than one lifecycle contributor."

Annotation 8.0 Element in LOM

This is a recommended element for the following purposes:

"This category provides comments on the educational use of this learning object, and information on when and by whom the comments were created. This category enables educators to share their assessments of learning objects, suggestions for use, etc."

"Implementers and educators SHOULD aspire to using the annotation category elements as they have the potential to significantly enhance the richness of the metadata instance by recording additional qualitative and quantitative information about the resource and its usage."

8.1 Entity = Entity (i.e. people, organisation) that created this annotation.
8.2 Date = Date that this annotation was created.
8.3 Description = The content of this annotation.

This may be very valuable in collecting the specific details of the validation document.

This is a very good presentation about the issues of metadata and some associated issues.
