Recording notes

A term used to describe an item depicted on an object/work or a subject covered. The purpose of keywords is to make objects easier to find in online searches. Several subject keywords can be assigned to an object. The data element should be repeatable and only one subject keyword should be assigned per element.

Keywords intended to place the object in a larger systematic or classificatory context should be recorded in the "Classification" data element. Terms given in the "Object type or designation" element should not be repeated in the "Subject keyword" element.

In addition to subjects and themes (in LIDO: <lido:subjectConcept>), individually identifiable persons or places depicted in an object or work may also be recorded as subject keywords. This should be done in separate fields so that they can be transferred to the LIDO elements <lido:subjectActor> and <lido:subjectPlace> during data export.

CARE: Persons from the communities of origin should be involved in the cataloguing work to allow for different interpretation models and possible interpretations. Alternative vocabularies are helpful to mitigate the Eurocentric perspective (see Terminology recommendation).

Comparison with relevant standards and database models

Standard	Element name	Text/URI	Repeatable	Obligation level	Comment
German Digital Library: Metadata requirements for data provision	(No match)	Not applicable	Not applicable	Not applicable
German Digital Library LIDO application profile (DDB-LIDO)	<subjectConcept>	Text (controlled vocabulary) and URI	Yes	Conditionally mandatory	Mandatory if sub-elements exist.
DFG Basic Data Record	Source Object Type of Content	Text and/or URI	Not specified	Recommended	In the DFG Basic Data Record, "Source Object Type of Content" is only recommended in the 'digital-mix' category. This only partly corresponds to the "Subject keyword" data element.
DFG Practical Guidelines on Digitisation: LIDO core metadata	Theme / Content <subjectSet>	Text and/or URI	Yes	Mandatory if available	In the DFG Practical Guidelines on Digitisation, the indexing of general terms in the LIDO element <subjectConcept> or of individual terms for persons/corporate bodies in <subjectActor>, places in <subjectPlace>, events in <subjectEvent>, objects in <subjectObject> or dates in <subjectDate> is mandatory if the information is available.
Europeana Data Model (EDM)	dc:subject	Text (controlled vocabulary) and/or URI	Yes	Conditionally mandatory	In the Europeana Data Model <dc:subject> (subject keyword/classification) OR <dc:type> (object type) OR <dcterms:spatial> (keyword [place/location depicted/represented]) OR <dcterms:temporal>(keyword [time depicted/as subject]) are mandatory.
EODEM application profile	(No match)	Not applicable	Not applicable	Not mandatory
digiCULT	Darstellung [eng.: Representation] Ikonographie [eng.: Iconography]	Text (controlled vocabulary) and/or URI	Yes	Recommended	The data element "Representation" in digiCULT is is a kind of element set consisting of iconography, depicted place, depicted person, depicted date and annotation.
museum-digital	Keyword or relation	Text (controlled vocabulary) and/or URI	Yes	Recommended	museum-digital recommends that keywords should be used in singular, lemmatised form; no diminutives or word formations on '-like' or '-shaped' should be used, and keywords should not be concatenated or embedded in hierarchical structures. See: https://de.handbook.museum-digital.info. In PUQI, a data quality measurement procedure and manual for improving data quality in museum-digital, three to nine keywords are recommended, but there is no strict separation between 'Subject keyword' and 'Classification' as required in the Minimum Record Recommendation.
