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’

11th May, Nicosia

‘Meta-messages’: an example

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

11th May, Nicosia

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!!)

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
