The metadata approach in eGovernmentThe purpose
InteroperabilityFree flow of information
![Page 5: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/5.jpg)
The metadata approach in eGovernment
Why interoperability?Improve quality: Connecting ”all” information and resources Improve possibilities for the use of information and
resources from different sources and stored in different ways
Minimize costs: Easy re-use of information and resources ”Full automatic” handling the information and
resources
![Page 6: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/6.jpg)

The metadata approach in eGovernment
What was/is the challengeInteroperability - free flow of information: not depending on media not depending on system not depending on sector or
administrative level not depending on content or type of
information
![Page 9: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/9.jpg)
The metadata approach in eGovernment
What was illustrated about free flow and free acces – interoperability - is only possible with:
Standardized metadata
![Page 10: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/10.jpg)
The metadata approach in eGovernment
The ideal situation A comprehensive metadata element model
and framework is defined and established – ´a priory
”Users” know about the model and framework and just pick from it when needed
The metadata model and framework in use is internationally standardized
![Page 11: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/11.jpg)
The metadata approach in eGovernment
The real situation Only some models exists – and they are
often not co-ordinated (mapped) If models exist they are often not in use by
actual working systems If there are common European models and
framework – there is only little knowledge about them
![Page 12: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/12.jpg)
The past in Denmark How was the situation
There was already launched several projects for services etc. Some very succesfull
But they was not co-ordinated In the metadata-area there was no common
eGovernment standard eGovernment was isolated islands of
information
![Page 13: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/13.jpg)
The past in DenmarkSome initiatives
OIO preliminary metadata survey – spring 2001 (OIO = Open public Information Online)
A decision for using XML when transporting data between IT-systems – summer 2001
An organization for the XML initiative The Infostructurebase was initiated. A XML-
schema and eGov standards repository
![Page 14: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/14.jpg)

2 years of work
The XML infostructure database was established – launched March 2003
The workgroups finished their initial standardization work
Several projects and work groups delivered XML schemas to the Infostructurebase describing data-interfaces

XML-initiative DenmarkDokForm group
The Danish Government WG for Information and Documentation
Tasks at the moment: Metadata standardization regarding
information – elements and encoding schemes
Metadata core for exchange between ERM systems
Standardization (mark-up) for documents and legislation
![Page 20: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/20.jpg)
DokForm groupHow do it work
Use international standards: Dublin Core MIReG (from EU IDA programme) Moreq (from EU IDA programme)Use local expertise: Experts in the group Hearing industry – solution vendors Hearing relevant community
![Page 21: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/21.jpg)
DokForm groupWhat was/are the obstacles
MIReG (Managing Information Resources for eGovernment) the EU-IDA work item was not finished. Risk: lack of international interoperability
An almost total lack of appropriate encoding schemes (except for dates and language). Risk: lack of interoperability
Standardization in areas with a lot of practise but no standards. Risk: a lot of discussion and some has to change registration rutines and perhaps gets extra work
![Page 22: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/22.jpg)
The metadata approach in eGovernment
A Danish example 1Task: Make a metadata core for exchange of
metadata between ERM systemsRessources: 7 meetings. 2 public hearing processes Time: A little yearResults: Agreement about 17 elements. And the
knowledge that many encoding schemes do not exist
![Page 23: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/23.jpg)
DokForm groupWhat is the outcome
Metadata core for exchange between ERM systems – in XML
OIO subject scheme – in XML XML schemes for the structure of letters,
mails, notes, agendas and minutes XML schemes for the generic structure of
Danish legislation Chosen the authority file for corporation an
d institution names (”encoding scheme”)
![Page 24: Metadata and eGovernment The Danish Approach and Experience](https://reader035.fdocuments.net/reader035/viewer/2022070411/5681482b550346895db54ee2/html5/thumbnails/24.jpg)
Standardization in the area of eGovernment information and
documentationFuture work
Endorsing MIReG Look more closely in the area of encoding
schemes A comprensive metadata model for an
almost complete ERM systems Maintaining the core for ERM systems for
special use
