SCIS data cleansing trial

David Feighan & Pru Mitchell

Data cleansing trial

November 2013

Using education metadata to align school resources to the curriculum

Responding to the challenges and maximising the opportunities:

a school library catalogue vocabulary renovation

metadata cleansingmetadata enhancing

we did both to create…

the glue that facilitates discovery of library collections to the curriculum

Step 1: metadata cleansing

SCIS subject headings

ScOT thesaurus

http://scot.curriculum.edu.au

Step 2: metadata enhancing

The process

What we found•37,009 out of 43,130 (86%) records had ISBN-like data available

•qualifiers in ISBN field are annoying, eg ;(hbk.) ;(pbk.) ; (trade) etc

•clean up of export before matching against SCIS database, egsome ISBN duplicates can be removed by tools, watch out for field data types, esp for ISBNs and BIBIDs, leading zeros

•how to be sure that 001 values were SCIS numbers

•reloading and overlay process

•time and server load

New vocabularies and new MARC tags

Use of 658 Curriculum Element field

TOTAL number of records with this field in WorldCat:

4,679 out of a total of 302,928,939 MARC records as of 1 Jul 2013

Overall number of Holdings: 63,847

Australian Cross curriculum priorities

• 282 x MARC records with “658 $bAsia and Australia’s engagement with Asia. $2ACARA Australian education vocabularies”

• 482 x MARC records with “658 $bAboriginal and Torres Strait Islander histories and cultures. $2ACARA Australian education” vocabularies”

• 324 x MARC records with “658 $bSustainability. $2ACARA Australian education vocabularies”

Using new vocabularies

• Improves catalogue metadata to facilitate discovery and make the catalogue easier to use.

• Adds curriculum metadata so the catalogue can be aligned to the curriculum and therefore user needs.

• Provides a potential seamless metadata link:– To external authoritative information sources.– From other interfaces such as Scootle back to a library’s

own online and print holdings.

Using new vocabularies

• The glue that links the links the print and online collections to the curriculum as well as…

• The metadata that can be used to facilitate discovery of online resources directly from collection signage.

Using new vocabularies and fields

Does your library system:

•Display the new field for data entry?

•Display the new field in OPAC?

•Index the new field?

•Include the new field in reports?

•Provide export/import profiles?

Next step: community metadata

SCIS looks to ingesting curriculum metadata

from community members

to share out to

others in the SCIS community
