What is Metadata?
11th May, Nicosia
Definition:- ‘Data about data’ or ‘Information about information’
Metadata is structured information that describes, explains, locates or makes it easier to retrieve, use or manage an information resource
...A better definition: -‘Structured information about any kind of resource, which is used to identify, describe, manage or give access to that resource’.
Metadata is keyto ensuring that
resources willsurvive and
continue to beaccessible into
the future
3 main types of Metadata: descriptive, structural and administrative (rights and preservation).Metadata can describe resources at any level of aggregation: a collection, a single resource, a component of a larger resource
What does Metadata do?
11th May, Nicosia
Metadata help to:-Facilitate discovery of relevant information-Organize resources-Facilitate interoperability and integration-Provide digital identification-Support archiving and preservation
Metadata describe:-WHO-WHAT-WHERE-WHY-HOW
A medium for the communication of knowledge and for data interpretation
Structuring the data
11th May, Nicosia
Importance of metadata to structure information for:- Access-Retrieval-Long term preservation
Necessity of :-Ontologies (represent knowledge as a set of concepts within a domain and the relationships between those concepts)-Metadata schemas (sets of metadata elements designed for a specific purpose, such as describing a particular type of information resource)

A knowledge communication framework
Necessity of a framework:
- to overcome any problems of data inconsistency;- to trace the information about the pipeline for creation of
the digital resource from the acquisition to publication;- to provide a detailed description of all the intermediate
passages;- importance of the ‘meta-messages’

‘Meta-messages’: an example

Digital Libraries Projects
the huge number digital information (born or converted)necessity to evaluate and operate solutions and policies in the preservation of this material for the next generations. Digital libraries: born to meet the need of conservation and preservation

CARARE
11th May, Nicosia
http://www.carare.eu/eng/Resources/CARARE-Documentation
Creating the CARARE Schema
Rich schema for archaeology & architecture– Reviewed standards and schemas already in use– MIDAS Heritage, the Core Data Index, LIDO, POLIS DTD
and CIDOC CRM. Created CARARE based largely upon MIDAS Heritage
& POLIS DTD– Heritage asset– Digital resource– Collection information– Activity
11th May, Nicosia
Challenges for Europeana and CARARE
Archaeology– Geo-spatial co-ordinates
• Site location – area?• INSPIRE Directive• Standard (WGS84)
– Dates• Time periods (not one date)
– Heritage Asset concept– ESE to EDM
• CARARE mapping to EDM (due for release in the summer)• ESE currently in use
11th May, Nicosia
3D in CARARE
CARARE is also the first project to provide 3D content to Europeana as 3D-PDF documents
The metadata can be mapped to the EDM without a change to the schema
3D-ICONs project (www.3dicons-project.eu)– Paradata

CARARE: STARC content

The CARARE Process
11th May, Nicosia
CARARE content in Europeana
February first data items appeared– >800,000 records from the SwNHB– The complete dataset has been
uploaded and covers objects such as rune stones, tombs, dwellings to archaeological sites. The records that appear in Europeana are in text format and contain information about each monument with a link to the original content held in the SwNHB databases

The Power of Metadata
Europeana Hackathon applications– http://pro.europeana.eu/hackathon-prototypes
Wiki Loves Monuments– NL CARARE Content provider asset register of monument
co-ordinates Europeana apps
– Map– Timeline (will need extending for CARARE!!)

Overview• Introduction to Metadata• A knowledge communication framework• Data preservation requirements• STARC metadata schema• Digital Libraries projects & Europeana • CARARE• Linked Heritage• Conclusions

Linked Heritage The project:- http://www.linkedheritage.org/- 30 months (April 2011 - September 2013) - 20 Countries and hundreds of collections
Aims:- To contribute with new content to Europeana (both public and private sector);- To enhance the quality content in terms of metadata richness, re-use and uniqueness;- To enable improved search, retrieval and use of Europeana content;
Facing issues:- Non standard descriptive terminologies- Lack of private sector and 20th century content- Preservation of complex metadata models within Europeana metadata schema
11 May, Nicosia
Linked Heritage: the scopes Provision of 3 million new metadata records to Europeana• Technical infrastructure• Organisational aspects• Content aggregation and coordination
Best practices for content enrichment• Linked Data• Persistent Unique identifiers• Metadata and standards• Public Private Partnership• Terminologies and Vocabularies
