LIDO v1.1 Public Beta - Lightweight Information Describing Objects ICOM-CIDOC LIDO Working Group ICOM-CIDOC LIDO Working Group 2020-12-04 ARTstor, Collections Trust, Deutscher Museumsbund - Fachgruppe Dokumentation, Deutsches Dokumentationszentrum für Kunstgeschichte - Bildarchiv Foto Marburg, digiCULT-Verbund eG, Institut für Museumsforschung (SMB-PK), J. Paul Getty Trust, Göttingen State and University Library, Zuse-Institut Berlin.

LIDO is an XML schema intended for delivering metadata, for use in a variety of online services, from an organization’s collections database to portals of aggregated resources, as well as exposing, sharing and connecting data on the web. Its strength lies in its ability to support the typical range of descriptive information about objects of material culture. It can be used for all kinds of object, e.g. art, cultural, technology and natural science and supports multilingual portal environments.

The LIDO schema is the result of a substantial redesign and enhancement of the CDWA Lite and museumdat schemas based on recommendations of the CDWA Lite/museumdat Working Group, community feedback and further CIDOC-CRM analysis. It mainly builds on CDWA and includes additional concepts to meet SPECTRUM requirements.

For more information on LIDO please refer to: http://www.lido-schema.org

The schema is developed at https://gitlab.gwdg.de/lido/development. LIDO v1.1 is backwards compatible with LIDO v1.0. For a summary of changes please refer to the repository’s README. The full history of LIDO can be found in http://www.lido-schema.org/schema/v1.0/lido-v1.0-specification.pdf, 2.3 History of the schema.

Creative Commons Attribution 4.0 International (CC BY 4.0) Abstract Schematron rules Allow free text or LIDO's concept elements (mutually exclusive) Some elements in LIDO v1.0 should be controlled in the future whereas they are free text elements in LIDO v1.0. To ensure backwards compatibility either a free text or a controlled term should be provided in a mutually exclusive way. Either a free text (incl. its attributes) OR a combination of skos:Concept, lido:conceptID and lido:term can be a child of , but not both at the same time. skos:Concept Ensures that only skos:Concept (and not another element/class from the SKOS namespace is used as a child element for concept(Mixed)ComplexType. Only skos:Concept should be used as direct child of from the SKOS namespace. Expansion of skos:Concept Ensures that when enriching a dataset with information retrieved via the URI provided in skos:Concept, only SKOS properties are added to the dataset. Only SKOS properties are allowed within skos:Concept. owl:sameAs Ensures that only owl:sameAs (and not another element/class from the OWL namespace is used as a child element for actorComplexType, placeComplexType and legalBodyRefComplexType. Only owl:sameAs should be used as direct child of from the OWL namespace. rightsType@type: generic or specific type A LIDO element holding lido:rightsType can either hold a generic or a specific type of right. Since a right can fall in only one of these categories, they are mutually exclusive.

can either hold a specific or a generic lido:rightsType (mutually exclusive).

Possible values for lido:rightsType@lido:type In LIDOv1.1 a lido:type attribute is introduced for lido:rightsType in order to discern generic rights and specific ones. This rule ensures that only the URIs for these two types of rights are used when @lido:type is set. @lido:type can either be omitted or must hold one of the following URIs: http://terminology.lido-schema.org/lido00920, http://terminology.lido-schema.org/lido00921.
