The CARARE metadata schema builds on existing standards and best practice from a number of different countries in Europe and the rest of the world.
The standards which form the background to the CARARE metadata schema include:
CIDOC Archaeological Sites Core Data Standard
The Archaeological Sites Core Data Standard was established by an international working group with the aim of facilitating communications between the national and international bodies responsible for the archaeological heritage, to assist the development of record systems and to facilitate research using archaeological site data.
Core Data Index to Historic Buildings and Monuments of the Architectural Heritage
Core Data Index as the "Recommendation on the co-ordination of documentation methods and systems related to historic buildings and monuments of the architectural heritage" was adopted by the Committee of Ministers of the Council of Europe on 11 January 1995. The basic aim of the Core Data Index is to make it possible to classify individual buildings and sites by name, location, functional type, date, architect or patron, building materials and techniques, physical condition, and protection status. It is not an end in itself, but a starting point to further information held in databases, documentation centres, and elsewhere that is necessary for the detailed understanding and care of individual monuments.
The CIDOC Conceptual Reference Model (CIDOC CRM) is the result of over 10
years work by the CIDOC Documentation Standards Working Group and CIDOC CRM
Special Interest Group, and is an ISO standard (ISO 21127 (2005)).
The CIDOC CRM is a formal standard that defines documentation concepts for the cultural heritage and the relationships between those concepts. It provides a flexible standard framework that cultural heritage data can be mapped to and provides a framework for semantic interoperability.
MIDAS Heritage is a data standard for information about the historic environment which was developed by English Heritage in collaboration with the UK Forum for Information Standards in Heritage and a number of heritage organisations in the UK building on the CIDOC Archaeological Sites Core Data Index and the CIDOC CRM. MIDAS Heritage covers the three main themes:
- Heritage assets – buildings, archaeological monuments, landscape areas, shipwreck sites, find-spots, artefacts and ecofacts.
- Activities – Field investigation, Research and Analysis, Management Activity, Casework and Consultation, Designation and Protection and also Historical events.
- Information sources – bibliographic sources, archive materials, management documentation, and narratives and syntheses (e.g. text plus images for educational purposes).
and the following supporting information:
- Spatial information – Location and map information
- Temporal information – Date and period
- Actor information – people, organisations and their roles
The POLIS DTD was produced as part of an EU funded Greek national research project to develop an interoperability framework for the cultural heritage. A series of DTDs were produced for different applications (including monument inventories, museums, archives, bibliographies etc) each derived from the CIDOC CRM. The Monument Inventory DTD was closely related to the core data index for archaeological sites.
LIDO – Lightweight Information Describing Objects is a metadata harvesting schema which was is the result of an international collaborative effort in the museums sector. LIDO is based on CDWA Lite, MuseumDat, the CIDOC CRM and SPECTRUM. LIDO is made up of a nested set of ‘wrapper’ and ‘set’ elements which structure records and contain ‘data elements’ which hold the information that is being harvested and delivered to the user of the service environment. There are 7 areas in a LIDO record for an object:
- Object identification
- Object classification
- Relations of the object
- Events – in which the object has taken part
- Rights work – information about the rights associated with the object, metadata and digital surrogate
- Record – basic information about the record
- Resource – information about the resource being supplied to the service environment (Europeana)
GIS (Geographic Information System) metadata
MIDAS Heritage complies with the UK GEMINI Discovery Metadata Standard, which specifies a set of metadata elements for describing geographic datasets (which is used by the UK’s GIgateway™ metadata service run by the Association for Geographic Information). English Heritage has work underway to implement the INSPIRE directive for GIS metadata before the end of 2010.
All dates in the CARARE schema conform with ISO 8601, i.e. they are specified largest temporal term first and according to the Gregorian calendar; e.g. 1981-04-05.
The CARARE schema builds on these standards and also the work of the members of the CARARE metadata working group, the DCU metadata team and the English Heritage Data Standards Unit including: Christos Papatheodorou, Phil Carlisle, Christian Ertmann-Christiansen, Kate Fernie, Maria Emilia Masci, Oliver Mamo, Börje Justrell, Sven Ole Clemens, Vassilis Tzouvaras, Dimitris Gavrilis, Stavros Angelis, Constantia Kakali, Giannis Tsakonas, Panos Constantopoulos, Costis Dallas, Sólborg Una Pálsdóttir, Effie Patsatzi, Lena Inger Larsen, Daniel Pletinckx, Nasos Drosopoulos, Vykintas Vaitkevičius, Rimvydas Laužikas, Phil Carlisle, Gillian Grayson and Stephen Stead.
