1 Metadata Acquisition with XML Case studies from the Swiss Federal Archives 9. October 2002 / Stephan Heuscher

2 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives2 Overview  Problems acquiring metadata  Why XML?  Featured Projects  Lessons learned  Conclusions

3 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives3 Problems acquiring metadata  Documentation  Data format  Data consistency  System borders  Money  Communication with stakeholders

4 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives4 Why XML? XML …  … is an open standard  … is self-explanatory  … is human-readable  … can be validated automatically  … has a broad software support  Most products feature XML support

5 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives5 Featured Projects SIARD  Archiving of relational databases  Manual generation of additional metadata  Metadata and content is stored in XML files AMDA  Manages metadata for audio data from the Swiss Parliament  Does not manage audio data  Import of XML metadata  Must provide a variety of export formats

6 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives6 Data and low-level metadata extraction SIARD (System Independent Archiving of Relational Databases) OracleMS-SQL???-DB Additional high-level descriptive metadata Digital Archive (to be built) Database regeneration

7 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives7 XML use in SIARD  SQL-99 (ISO/IEC 9075)  Low-level data description  Structure  Datatypes  Constraints  XML  High level metadata  Table content (thin wrapper)

8 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives8 Data Logic (SQL) CREATE TABLE "FLUGLE"."CLASS" ( "CLASS_ID" NATIONAL CHARACTER VARYING(20) NOT NULL, "SCHEDULE_ID" NATIONAL CHARACTER VARYING(20), "CLASS_BUILDING" NATIONAL CHARACTER VARYING(25), "CLASS_ROOM" NATIONAL CHARACTER VARYING(25), "COURSE_ID" NATIONAL CHARACTER VARYING(5), "DEPARTMENT_ID" NATIONAL CHARACTER VARYING(20), "INSTRUCTOR_ID" NATIONAL CHARACTER VARYING(20), "SEMESTER" NATIONAL CHARACTER VARYING(6), "SCHOOL_YEAR" TIMESTAMP(0) ) CREATE TABLE "FLUGLE"."CLASS_LOCATION" ( "CLASS_BUILDING" NATIONAL CHARACTER VARYING(25) NOT NULL, "CLASS_ROOM" NATIONAL CHARACTER VARYING(25) NOT NULL...

11 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives11 AMDA (Audio MetaData Acquisition) Online parliament session metadata (XML) AMDA Webinterface Metadata Audio data Digital Archive Unified XML import Access DB (to be built)

12 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives12 XML use in AMDA  Import  XSLT transformation to common format  Online metadata  Legacy data (Access database)  Export  Raw XML output transformed using XSLT

15 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives15 Lessons learned  Transforming and reformatting of XML data is easy  Documentation and data integrity are crucial  Agree on rules and standards for XML formats early  Stakeholders’ uses of XML differ greatly

16 09.10.2002Urbino2002.ppt; Stephan Heuscher; Swiss Federal Archives16 Conclusions  XML  is not a preservation strategy  is only a technology  is too new for a common understanding  XML provides tools and techniques for a concise metadata management  Working solutions need both XML and non-XML experience  Most problems are still of human nature
