4 Why a standard format for contributing content? DDB Europeana LIDO (museumdat) LIDO (museumdat) Communication between cataloguers and builders of cultural heritage systems Collection Management Systems: Adlib, APS, digicult.dokbase, digicult.web, easydb, Faust, First Rumos, Gallery Systems, GOS, Hida, Imdas, MuseumPlus, Union Catalogues and Portals BAM, Bildindex, museumdigital, Museumsportal Nord, Museumsportal Saarland,...

5 Why a standard format for contributing content? Increasing relevance of internet presence for museums and other collections Increasing necessity to integrate your data into union catalogues and portals: facilitate resource discovery in a cross-collection and even cross-sectoral (archives, libraries, museums) manner Increasing requests to make your information available for the Semantic Web / Linked Data initiatives Introduction The broad view standards Wikipedia - Anjeve, Richard Cyganiak

6 Introduction The broad view standards It s all about creating a consistent information base making your information understandable outside of your collection database / your home context! Need for convenient instruments to provide cultural collection information from different collections / object classes from different data structures from different software systems

7 Introduction The broad view standards There are different layers to be considered Publication / Exchange Protocols Data Structure Standards Data Content Standards Data Value Standards

8 Introduction The broad view standards http OAI-PMH CDWA, Spectrum CDWA Lite, museumdat, Spectrum XML, LIDO Publication / Exchange Protocols Data Structure Standards Data Format as XML Schema (or possibly as RDF Schema) CIDOC-CRM as reference model CCO Data Content Standards GND, AAT, Iconclass, LCSH, ULAN, TGN SKOS, FOAF Data Value Standards Data Format as XML Schema / RDF Schema

9 The broad view standards Reference: CIDOC-CRM / ISO CIDOC-CRM / ISO in less than a nutshell Developed within CIDOC, the Documentation Committee of the International Council of Museums (ICOM) Is a formal domain ontology for cultural heritage information: Describes the things that the cultural heritage sector deals with and how these things relate to each other Expressed as an object-oriented schema

10 The broad view standards Reference: CIDOC-CRM / ISO Example CRM E22 Man Made Object P108 was produced by E12 Production P4 has time-span P10 falls within E52 Time Span P79 beginning is qualified by P80 end is qualified by E62 String E62 String Kragenflasche E4 Period P2 has type E55 Type Neolithic

11 The broad view standards Reference: CIDOC-CRM / ISO CIDOC-CRM / ISO in less than a nutshell Establishs a conceptual basis for integration and access to cultural heritage information: semantic glue LIDO EAD CRM MODS

12 The broad view standards Reference: CIDOC-CRM / ISO When Where Who What Events

13 From CDWA Lite to museumdat to LIDO: LIDO is the result of a joint effort of the CDWA Lite, museumdat, and Spectrum communities to establish one common, single schema, based on: Experiences and feedback from practical implementation and use of CDWA Lite and museumdat Further CIDOC-CRM analysis The broad view standards Contributing Content Requirements of SPECTRUM aimed at content delivery for publication

14 The broad view standards Contributing Content : cdwalite-xsd-public-v1-1.xsd museumdat-v1.0.xsd spectrum-3.1.xsd LIDO v1.0

15 The broad view standards Contributing Content ICOMs International Committee for Documentation, provides the museum community with advice on good practice and developments in museum documentation. CIDOC 2009: Implementation of the new CIDOC Working Group Data harvesting and interchange CIDOC 2010 ( November): Release of LIDO v1.0 as common, single schema for contributing content to cultural heritage repositories

18 Purpose Why Zoological Museums Archaeological Museums Medical and Pharmaceutical Collections Museums of Cultural History Botanical Gardens Museums of Fire Fighting Computer Collections Theatre History Collections Geological and Mineralogical Museums Art Museums

19 Purpose What it is XML Schema for Contributing Content to Cultural Heritage Repositories For delivering metadata, for use in a variety of online services, from an organization s online collections database to portals of aggregated resources as well as exposing, sharing and connecting data on the web. Intended to represent the full range of descriptive information about museum objects, e.g. art, cultural, technology and natural science. It supports multilingual environments.

20 Purpose What it is NOT LIDO is NOT A fully developed data exchange format. A format designed for proper cataloging it is not intended to be used as a basis for a collection management system or to support loan and acquisition activities.

21 Schema Design Construction Principles Provide a specification and related XML schema that describes cultural materials appropiately Individual data providers can decide on how light or how rich they want their contributed metadata records to be Allow for delivering data and resources / digital surrogates relating to your objects Include links from contributed metadata back to records in their 'home' context

22 Schema Design Construction Principles Cont.: Allow for delivery of full information: a record can include all the necessary information for display and retrieval of your object Allow for identification of each referenced entity, e.g. provide references to controlled vocabulary and authority files. Provide optimised metadata for retrieval on one hand and for display on the other -> distinction of display and indexing elements

23 Schema Design Groups of Information Descriptive and administrative information groups in LIDO - Object Classifications Object / Work Type (mandatory) Classification -Object Identifications Title / Name (mandatory) Inscriptions Repository / Location State / Edition Object Description Measurements -Events Event Set -Relations Subject Set Related Works -Administrative Metadata Rights Record (mandatory) Resource

25 Schema Design Multilinguality Full support of multilinguality - Example xml:lang on high-level element descriptivemetadata Material Ton@de clay@en

26 Schema Design References to Controlled Vocabulary Index - Gothic style - Gotik - Trecento <skos:concept rdf:about=" <skos:preflabel xml:lang="en">gothic style</skos:preflabel> <skos:preflabel xml:lang="de">gotik</skos:preflabel> <skos:altlabel xml:lang= de">trecento</skos:altlabel> <skos:broader rdf:resource=" </skos:concept> SKOS RDF over Webservice Portal metadata enrichment Using Webservice / REST / SRU: [or lexical value Gotik in the concept scheme Style ] LIDO-XML <lido:classification type= Style > <lido:conceptid lido:type="url"> <lido:term xml:lang="de">gotik</lido:term> </lido:classification>

56 Object Classification objectworktype: Aquarell specification.pdf Bezeichnung, die einen spezifischen Objektoder Werktyp identifiziert. Das Element hat Schlagwortcharakter und sollte sich auf fachwissenschaftliche Terminologien beziehen. Es ist wiederholbar, um alle oder die wichtigsten Schwerpunkte einer Sammlung identifizieren zu können.

57 Object Classification classification: Zeichnung / Grafik type: Hessische Systematik / subject group [a theoretical possibility] Ein Begriff, der ein Objekt in einem größeren Kontext kategorisiert. Diese Kategorie entstammt einer Systematik, die Objekte mit ähnlichen Charakteristika nach einheitlichen Gesichtspunkten gruppiert. Diese Gruppierung / Systematisierung kann nach Materialien, Form, Funktion, Herkunft, zeitlicher / stilistischer Einordnung, nach kulturellem Kontext usw. vorgenommen werden. Zusätzlich zur sachsystematischen Einordnung können auch organisatorische Einteilungen innerhalb des Museums angegeben werden (z.b. der hausinternen Sammlungsstruktur). Wenn ein Objekt mehreren Klassifizierungen zugeordnet wird, wiederholen Sie das Element.

84 The broad view standards Data Content and Structure SPECTRUM is the UK and international standard for Collections Management. It consists of two main sections: Procedures Information requirements SPECTRUM XML Schema provides a standard format for exchanging object records between different collections management systems. Its objective is the whole world of museum documentation and collection management.

85 Cataloguing Cultural Objects Developed within a project of the VRA: is a manual for describing, documenting, and cataloguing cultural works and their visual surrogates. intends to inform the decision making processes of cataloguers and builders of cultural heritage systems. employs generic concepts that can be used with any metadata element sets. E.g. used in the MARC/AACR world of The Morgan Library and Museum New York See the Ten Key Principles of CCO The broad view standards Data Content

86 The broad view standards Categories for the Description of Works of Art Data Structure CDWA describes the content of art databases by articulating a conceptual framework for describing and accessing information about works of art, architecture, other material culture, groups and collections of works, and related images. It includes 532 categories and subcategories. CDWA Lite is an XML schema to describe core records for works of art and material culture based on CDWA and CCO. CDWA Lite records are intended for contribution to union catalogs and other repositories using the Open Archives Initiative (OAI) harvesting protocol.

87

88 The broad view standards Contributing Content Why not just use Dublin Core? Dublin Core, currently the preferred schema for lots of repositories and especially for OAI harvesting, was designed for Web resource discovery. It is not appropriate for describing cultural materials because: its elements are broad and generic, usable for describing a wide range of resources but are not able to capture in a meaningful manner the semantics of cultural heritage information instead DC encourages mix-up of semantically different information in same elements Unsatisfying retrieval results!

89 From CDWA Lite to museumdat to LIDO: Challenges I: The broad view standards Contributing Content CDWA Lite is very much focused on fine arts: it s starting point was eventually delivering metadata from an art collection (the Getty museum) to a digital library on art (ARTstor) Need of a format that covers object data of manifold provenance such as cultural history, natural history, history of technology

90 From CDWA Lite to museumdat to LIDO: Challenges II: CDWA Lite is very much focused on north american data standards: CDWA as data structure standard AAT, TGN, ULAN as data value standards CCO as data content standard The broad view standards Contributing Content Need of generalizing the scope for further standards and other languages

91 From CDWA Lite to museumdat to LIDO: The broad view standards Contributing Content WG Data exchange, German Museum Association: Event-oriented approach of CIDOC-CRM allows for generalizing the format for use with various object data CIDOC-CRM as ISO standard (ISO 21127) is the reference model a standard metadata format should be CRM compliant museumdat is a reconfiguration of CDWA Lite based on CIDOC-CRM analysis
