LIDO: Lightweight Information Describing Objects is an XML harvesting schema. It is the result of a collaborative effort of international stakeholders in the museum sector, starting in 2008, to create a common solution for contributing cultural heritage content to web applications.

LIDO is based on CIDOC-CRM Conceptual Reference Model (CRM). It comes from the integration between CDWA Lite and museumdat metadata schemas and it is based on SPECTRUM standard. Being an application of the CIDOC-CRM, it provides an explicit format to deliver (museum’s) object information in a standardised way.

LIDO is a schema intended for delivering metadata, for use in a variety of online services, from an organisation's online collections database to portals of aggregated resources, as well as exposing, sharing and connecting data on the web.

MINT implemented LIDO as intermediate harvesting schema. Initially conceived for museum sector needs, it is currently used in cross-domain contexts proving its adaptability and effectiveness in preserving the integrity of rich metadata.

Linked data

Linked data is a pattern for hyperlinking machine-readable data sets to each other using Semantic Web techniques, especially via the use of RDF and URIs. Enables distributed SPARQL queries of the data sets and a browsing or discovery approach to finding information (as compared to a search strategy). Linked Data is intended for access by both humans and machines. Linked Data uses the RDF family of standards for data interchange (e.g., RDF/XML, RDFa, Turtle) and query (SPARQL). If Linked Data is published on the public Web, it is generally called Linked Open Data (See: W3C Government Linked Data Working Group: Linked data Glossary).

Linked Heritage aggregation

The Linked Heritage aggregation includes data from archives, museums, libraries, research centres and universities (see: Linked Heritage partners and contributors), and covers 3D models, manuscripts, ancient prints, medieval antiquities, archaeological artefacts, monuments, Greek and Latin inscriptions, fossils, ancient and modern paintings, ethnographic collections and more. According to Europeana blog, the Linked Heritage aggregation is one of Europeana's biggest aggregators.

Linked open data

Linked open data (LOD) is a growing movement for organisations to make their existing data available in a machine-readable format. This enables users to create and combine data set and to make their own interpretations of data available in digestible formats and applications. LOD is all about opening up information and data as well as making it possibile to use and reuse it.

LOD is domain-independent.

LOD drive the following 10 principles:

1.: Data must be complete

2.: Data must be primary

3.: Data must be timely

4.: Data must be accessible

5.: Data must be machine-processable

6.: Access must be non-discriminatory

7.: Data formats must be non-proprietary

8.: Data must be license-free

9.: Permanance

10.: Usage costs

The 5 stars by Sir Tim Berners-Lee:

1.: Information is available on the Web (any format) under an open license

2.: Informationis available as structered data (e.g. Excel instead of an image scan of a atable)

3.: Non-proprietary formats are used (e.g CSV instead of Excel)

4.: URI identification is used so that people can point at an individual data

5.: Data is linked to other data to provide context.

Data represent "things" (known as resources) that can can be anything, including: objects, archival material, books and other document types, media files, places, persons, and organisations, events and concepts (such as material, colour, and style). RDF is the standard in linked data used to describe the "things".

Linking open data cloud

Linking open data cloud is a group that catalogs data sets that are available on the Web as Linked Data and contain data links pointing at other Linked Data sets. These data sets have been published as Linked Data by contributors to the Linking Open Data community project and other individuals and organisations. The catalog of the LOD cloud data sets is hosted by Datahub, the free, powerful data management platform from the Open Knowledge Foundation, based on the CKAN data management system. It is used to generate the Linking Open Data Cloud diagram maintained by Richard Cyganiak (DERI, NUI Galway) and Anja Jentzsch (HPI). The LOD cloud data set catalog is also used to generate the statistics provided in the State of the LOD Cloud document.

Currently the LOD Cloud consists of 340 data sets.
