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: www.lido-schema.org
Prepared for CIDOC LIDO Working Group by LIDO-DE Working Group.
The schema is developed at 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 lido-v1.0-specification.pdf, 2.3 History of the schema.

Schematron constraints for LIDO Version 1.1
Either free text or index element
In LIDO v1.1 some text elements are extended to conceptComplexType
in order to foster controlled indexing in the future. To enable backwards
compatibility either elements of textComplexType or elements of
conceptComplexType
are allowed. Note that the elements are defined to be mutually exclusive.
Asserts that either an element based on textComplexType or an element
based on conceptComplexType is used for , but not both at the same time.
conceptComplexType allows only skos:Concept from SKOS namespace
Asserts that only skos:Concept and not any other class from the SKOS namespace is used for
statements about a LIDO element based on conceptComplexType.
Only skos:Concept should be used as embedded class in from the SKOS namespace.
skos:Concept allows only SKOS properties
Asserts that only properties in the domain or range of the skos:Concept
Class are used for statements about a LIDO sub-element of conceptComplexType.
Only SKOS properties in the domain or range of the skos:Concept Class are allowed.
ComplexType allows only owl:sameAs from OWL namespace
Asserts that only owl:sameAs and not any other property or class from the
OWL namespace is used to state identity equivalence in instances of LIDO elements contained in
actorComplexType,
eventComplexType,
legalBodyRefComplexType,

rightsHolderComplexType.
Only owl:sameAs should be
used as embedded property of from the OWL namespace.
Values for rightsType@type
A LIDO rightsType element can either hold the type attribute 'generic' or 'specific', respectively.
Since a generic rights type and a specific rights or license statement fall into different logical
categories, these types are mutually exclucive.
can either hold a specific or a generic lido:rightsType@lido:type (mutually exclusive). If lido:rightsType@lido:type is used in , it must be used in all .
Possible values for lido:rightsType@lido:type
In LIDO v1.1 a type attribute is introduced for the LIDO rightsType element
in order to discern generic rights and specific ones.
This rule asserts that only the URIs for these two types of rights are used when the type attribte 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.

An index element indicating the kind of place based on political or physical division,
including physical features such as pieces of land or bodies of water, or mobile objects such as ships.

"political" or "geographical", corresponding, for instance, to the TGN Record Types
"administrative" and
"physical".
