3. New Acquisitions List (1)
Design considerations:
No need to build database
Static files, one set for each week
Web interface by Perl script
Weekly static files generated by Perl script as a batch job at night

5. New Acquisitions List (3)
XSLT transformation of IIIRECORD to New Acquisitions Record
Requires a few passes of XSLT
Locally developed tool to convert EACC codes in “braced form” to UTF-8
Sample IIIRECORD
Resulting Record after XSLT transformation

6. New Acquisitions List (4)
Conclusion:
By using Perl scripts and XSLT stylesheets, list of XML formatted bibliographic records extracted from INNOPAC can be transformed into two completely different outputs (views), namely HTML web page and RSS news feed.

7. Electronic Journals Online (1)
Design considerations
Require a database (on Tamino)
Metadata schema design
Indexing design
Weekly updating by Perl script
Decided to use Perl module of LibXML, instead of XSLT stylesheets

9. Electronic Journals Online (3)
Metadata Design
Decided not to use Dublin Core
Internal metadata - not for exchange with external systems
Programming overhead to incorporate DC
Requires extension of DC in order to markup MARC Tag 856, the hypertext link to the electronic resources
Hong Kong University of Science & Technology Library

10. Electronic Journals Online (4)
Decided not to use RDF
Due to the same reasons above; although it can resolve the Tag 856 markup problem that DC has.

11. Antique Maps and Theses (1)
HKUST Theses
Design considerations
Both databases are on Tamino
Metadata as XML documents
Hypertext links to PDF files
Hong Kong University of Science & Technology Library

12. Antique Maps and Theses (2)
Multi-script Considerations
Non-English characters:
Diacritics
Mathematical symbols and formulas
Greek alphabet
CJK
XML is UTF-8 by default
Tamino stores XML documents in Unicode

13. Antique Maps and Theses (3)
Unicode and UTF-8 Explained:
Developed by Unicode Consortium ( since 1991.
A character coding system of written texts of diverse languages.
Latest version is 4.0, released in 2003.
Has 96,382 characters. 82,270 of them are CJK characters (including Hangul).
Hong Kong University of Science & Technology Library

14. Antique Maps and Theses (4)
Diacritics – Combining Characters to be positioned relative to an associated base character.
UTF-8 transforms a Unicode scalar value to a sequence of 8-bit bytes. English alphabets are one byte, CJK ideographs are three bytes. a ȧ

15. Antique Maps and Theses (5)
Example of UTF-8 transformation:
Latin character A has a Unicode scalar value of U It is transformed to
\x41.
Greek alphabet α has a Unicode scalar value of U+03B1. It is transformed to \xCE\xB1.
Chinese character 中 has a Unicode scalar value of U+4E2D. It is transformed to \xE4\xB8\xAD.
