Overview

This document is intended to be an easy-to-read reference the currently recommended terms of the Latimer Core Standard. This document is not part of the standard. It draws on the term names and definitions from the normative part of the standard and combines them with comments and examples that are not normative, but that are meant to help people to use the terms consistently. The category LatimerCore corresponds to the parent class, which is a special category term used to group the rest of the terms for convenience. Comprehensive metadata for current and obsolete terms in human readable form are found in a list of terms document. List of files and types can be found in the Latimer Core repository.

Label	Latimer Core Scheme
Definition	A grouping of multiple ObjectGroups for a particular use case, purpose or implementation.
Notes	Where the same objects within the same collection might be described by more than one ObjectGroup for different purposes (for examples, a 'Darwin Fossil Mammals' collection description might overlap with a 'Offsite Palaeontology' collection description), this class can be used to distinguish between them and avoid double-counting of metrics in queries against the data.

ltc:basisOfScheme Property
Qualified Term	ltc:basisOfScheme
Label	Basis Of Scheme
Definition	A summary of the basis or purpose for the LatimerCoreScheme.
Notes	This property is intended to summarise the reason for grouping a number of ObjectGroups within the LatimerCoreScheme, and the purpose for which the data is intended to be used. This may also be reflected in the terms and metrics defined using the SchemeTerm and SchemeMeasurementOrFact classes respectively. Using this approach, standard and reusable profiles within the wider Latimer Core standard may be constructed for common collection descriptions use cases.
Examples	Accession Inventory Expedition Digitisation planning Collections assessment Institution Collections registry

Notes	If isDistinctObjects is set to 'true', then no collection object should be covered by more than one object group within the LatimerCoreScheme. This is important for aggregating and reporting on metrics such as object counts, as it prevents any physical object from being counted more than once.
Examples	true false

ltc:schemeName Property
Qualified Term	ltc:schemeName
Label	Scheme Name
Definition	A short descriptive name given to the LatimerCoreScheme.
Examples	NHM Collections Inventory Index Herbariorum European Darwin Collections

Notes	For some use cases, this property can also be used to reflect the type of value being stored (e.g. a count, or a percentage).
Examples	mm C km ha count percentage category

dwc:measurementValue Property
Qualified Term	dwc:measurementValue
Label	Measurement Value
Definition	The value of the measurement, fact, characteristic, or assertion.
Notes	In the Collection Description standard, this field is constrained to only accept numeric values in order to better support the aggregation of quantitative metrics. For any non-numeric values, and metrics where the scale is a numeral that cannot be used in any calculations the measurementFactText property should be used instead.
Examples	45 20000 1 14.5

Examples	Open to the public

ltc:description Property
Qualified Term	ltc:description
Label	Description
Definition	A free text description or narrative about the collection.
Notes	Use this field to record information about the collection in a human-readable, narrative style to introduce the main characteristics of the collection to someone unfamiliar to it. It may include additional information or re-state information held elsewhere in the collection description record - for example, for more atomic, categorised textual descriptions and narratives the MeasurementOrFact class should be used.
Examples	The Chicago Academy of Sciences holds material documenting the biodiversity of Midwest / Western Great Lakes region from the 1830s to the present, and includes comparative and historic material collected across North America. These collections include zoology, botany, earth sciences, cultural, audiovisual, and archives.

Definition	Material denotes the raw substance(s) from which the object is formed, in whole or in part.
Notes	This definition maps roughly to the concept of E57 'material' from the CIDOC CRM: https://cidoc-crm.org/Entity/E57-Material/version-7.1.1. The object, or artefact could contain biological parts, for example jewellery made of amber with insects in, or cloaks made of bird feathers. It should not be used for taxonomic identifications.
Examples	Biological body Organism material (cp. objectType = Organism product) Viable cells Protein RNA DNA, etc.

ltc:objectType Property
Qualified Term	ltc:objectType
Label	Object Type
Definition	High-level terms for the classification of curated objects.
Notes	Hands-on, practical attributes classifying the stored curated objects. You will expect to find these kinds and types of objects when you go to and access their storage location. This should not be used for classifying objects by taxon. The best way to do that is to use the Taxon class (formal taxonomy and vernacular names) or ObjectClassification class (informal classification).
Examples	if baseTypeOfObjectGroup = MaterialEntity: Specimen Tissue Culture HTS Library Lysate Environmental sample Extracted/Preserved DNA/RNA Microscope slide Spore print Macrofossil Mesofossil Microfossil Oversized fossil; if typeOfObjectGroup = Non-biological: Macro-object Micro-object Oversized object Cut/polished gemstone Core Fluid Hazardous material/object Mixed; if baseTypeOfObjectGroup = InformationArtefact: Text Audio Visual

ltc:period Property
Qualified Term	ltc:period
Label	Period
Definition	Used to describe prehistoric or historic periods.
Notes	Often used to describe prehistoric or historic periods, but also geopolitical units and activities of settlements are regarded as special cases of Period. However, there are no assumptions about the scale of the associated phenomena. In particular all events are seen as synthetic processes consisting of coherent phenomena. This property maps to the Period class of the CIDOC-CRM conceptual reference model (http://www.cidoc-crm.org/Entity/e4-period/version-7.1.1).
Examples	Neolithic Period Ming Dynasty McCarthy Era

ltc:preparationType Property
Qualified Term	ltc:preparationType
Label	Preparation Type
Definition	A term used to classify or describe an object that indicates the actions that have been taken upon it and/or the processes it has been put through to prepare it for scientific use or study.
Notes	These attributes commonly identify the parts or states that are the outcome of the preparation process, which produced the curated object. This can be the same as PreservationMethod (e.g. Bone), but is not always. For cultural collections terms such as 'bowl', 'textile' are appropriate at this level. This should not be used for classifying objects by taxon. The best way to do that is to use the Taxon class (formal taxonomy and vernacular names) or ObjectClassification class (informal classification).
Examples	if objectType = Specimen or Part of entity: Bones Eggs Pollen Muscle Leaf Blood Skins Shells Wood, ... ; if typeOfObjectGroup = human-made: Bowl Textile, ...; if typeOfObjectGroup = digital: txt jpg mp4, ...; etc

ltc:preservationMethod Property
Qualified Term	ltc:preservationMethod
Label	Preservation Method
Definition	A term used to classify or describe an object that indicates the primary or most recent action, measure or process that has been used in order to preserve the objects in the collection for long-term storage.
Notes	Preservation method generally describes the final storage state. Not intended to be used as the fossilization method. Use preservationMode for that. This field is intended to be use where a collection has a single or prominent preservationMethod. We recommend the Arctos PART_PRESERVATION vocabulary (https://arctos.database.museum/info/ctDocumentation.cfm?table=CTPART_PRESERVATION). For herbarium sheets use 'dried_pressed'. If an alcohol collection uses mixed percentages use 'alcohol'.
Examples	dried dried_pressed dried_pinned Dried assemblage Dried - not assembled Dry preserved papered/packaged slide box Skeletonized Tanned mounted Slide mount Embedded gum_arabic Blood sampling cards (biomedical) Fluid preserved Alcohol, formaledhyde glycerin EDTA frozen / cryopreserved Cryopreserved / frozen - 80C refrigerated freeze_dried Surface coating SEM stub Stasis cell culture axenic culture viable cells Controlled atmosphere Climate controlled conditions Non climate controlled conditions no_treatment, etc.

ltc:preservationMode Property
Qualified Term	ltc:preservationMode
Label	Preservation Mode
Definition	The means by which a palaeontological specimen was preserved or created e.g. body, cast, mold, trace fossil, soft parts mineralised etc.
Notes	This property should be only used in association with ObjectGroups that contain paleontological material. It is aligned with the concept of preservationMode in ABCD(EFG) (https://efg.geocase.eu/documentation/html/efg.html#element_PreservationMode_Link03032878).
Examples	adpression/compression body cast charcoalification coalified concretion dissolution traces mold/impression permineralised recrystallised soft parts trace

ltc:typeOfObjectGroup Property
Qualified Term	ltc:typeOfObjectGroup
Label	Type Of Object Group
Definition	Additional information that describes the object(s) in the collection.
Notes	High-level information that enables the finding of the group and/or its object(s) in searches by users on the web using attributes commonly of interest. Recommended best practice is to use a controlled vocabulary. Terms such as soil, pollen, faeces, muscle, genomic DNA are currently put in preparationType.
Examples	if baseTypeOfObjectGroup = MaterialEntity: Living Preserved Fossilized Non-biological Human-made; if baseTypeOfObjectGroup = InformationArtefact: Digital Physical

dwc:degreeOfEstablishment Property
Qualified Term	dwc:degreeOfEstablishment
Label	Degree of Establishment
Definition	The degree to which an Organism survives, reproduces, and expands its range at the given place and time.
Notes	Some preserved collections are specifically created from cultivated or captive organisms, or perhaps from rare vagrants. Recommended best practice is to use controlled value strings from the controlled vocabulary designated for use with this term, listed at http://rs.tdwg.org/dwc/doc/doe/. For details, refer to https://doi.org/10.3897/biss.3.38084.
Examples	native captive cultivated released failing casual reproducing established colonising invasive widespreadInvasive

ltc:OrganisationalUnit ltc:hasAddress ltc:hasContactDetail ltc:hasIdentifier ltc:hasMeasurementOrFact ltc:hasParentOrganisationalUnit ltc:hasPersonRole ltc:hasReference ltc:organisationalUnitName ltc:organisationalUnitType

Qualified Term	ltc:OrganisationalUnit
Label	Organisational Unit
Definition	A unit within an organisational hierarchy which may be at, above or below the institutional level.
Notes	This class can represent any level of organisational unit, incorporating institutions (e.g. a museum), higher units (e.g. a university to which a museum belongs) and more detailed structures (e.g the departments and divisions within a museum). It can be used to arrange these different units at different levels into a hierarchical structure. This class combines aspects of both class org:Organization (https://www.w3.org/TR/2014/REC-vocab-org-20140116/#org:Organization) and class org:OrganizationalUnit (https://www.w3.org/TR/2014/REC-vocab-org-20140116/#org:OrganizationalUnit) from the W3C Organization Ontology ORG (https://www.w3.org/TR/2014/REC-vocab-org-20140116/#overview-of-ontology). Recommended best practice is to associate a unique, persistent organisational identifier (PID) with each created organisational unit. This will allow an unambiguous and continual identification of the unit, as well as the creation of organisational hierarchies. Existing providers of PIDs for organisations are, e.g. https://grid.ac/ and https://ror.org/. The provision of organisational PIDs might be extended to intra-organisational units in the future. Properties of Class: Identifier can be used to add identifier information for organisational units.

In the Collection Description standard, a use of this is to list named subcollections of a larger collections at a time when the resources might not be available to create a full Collection Description for each of them. If at a later point a Collection Description record is created for the subcollection, an identifier can be added to the relatedResourceID property to maintain the same relationship.
Examples	FMNH Mammals TNHC Vertebrates Sloane Herbarium Grant Southwest Ceramics Collection

ltc:relatedResourceType Property
Qualified Term	ltc:relatedResourceType
Label	Related Resource Type
Definition	The class or property within Latimer Core, or class, property or less formal concept outside of the Latimer Core standard, that is represented by the related resource.
Notes	This property can be used to explicitly define the type of resource that the ID stored in the relatedResourceID property references, either to support IDs that don’t fully resolve and provide contextual metadata, or just for information purposes. It can also provide context for use cases where the relatedResourceName is used rather than the relatedResourceID to define the target, for example to attach a simple list of the names of related collections to an ObjectGroup.
Examples	http://rs.tdwg.org/ltc/terms/ObjectGroup http://rs.tdwg.org/ltc/terms/Taxon http://rs.tdwg.org/ltc/terms/objectType http://rs.tdwg.org/dwc/terms/Occurrence, Collection

Notes	This class can be used to specify the qualitative and quantitative metrics that will be included in the LatimerCoreScheme using the MeasurementOrFact class, and dictate whether each will be mandatory and/or repeatable. This information can be used by software and queries to constrain and validate the Latimer Core dataset, and determine how and whether metrics can be aggregated and reported. The schemeMeasurementType property should correspond to the measurementType property of the MeasurementOrFact class in order to make the relevant association between the scheme definition and the stored data.

ltc:hasIdentifier Property
Qualified Term	ltc:hasIdentifier
Label	Has Identifier
Definition	This property refers to one or more related instances of the Identifier class.

Examples	true false

ltc:schemeMeasurementType Property
Qualified Term	ltc:schemeMeasurementType
Label	Scheme Measurement Type
Definition	A category of quantitative metric or qualitative fact that can be included in the LatimerCoreScheme.
Notes	The schemeMeasurementType should correspond to, and be used to catalogue and/or constrain, the values that can be used in the measurementType property of the MeasurementOrFact class.

ltc:SchemeTerm ltc:hasIdentifier ltc:hasReference ltc:isMandatoryTerm ltc:isRepeatableTerm ltc:termName

Qualified Term	ltc:SchemeTerm
Label	Scheme Term
Definition	A Latimer Core term used by the LatimerCoreScheme and the rules relating to its application.
Notes	This class can be used to define which of the terms (classes and/or properties) within the standard (e.g. GeographicContext, Taxon, preservationMethod) are expected to be used within the scheme, and specify whether they're mandatory and/or repeatable. This information can be used by software and queries to validate the data and understand the rules by which metrics can be reported against the specified term.

ltc:hasIdentifier Property
Qualified Term	ltc:hasIdentifier
Label	Has Identifier
Definition	This property refers to one or more related instances of the Identifier class.

ltc:hasReference Property
Qualified Term	ltc:hasReference
Label	Has Reference
Definition	This property refers to one or more related instances of the Reference class.

ltc:isMandatoryTerm Property
Qualified Term	ltc:isMandatoryTerm
Label	Is Mandatory Term
Definition	A flag to designate whether it is mandatory or optional for all ObjectGroups in the LatimerCoreScheme to include or be linked to valid data for the class or property defined in the termName property.
Notes	This flag can be used for software automation and data validation. For example, if the termName is 'preservationMethod' (a property) and isMandatoryTerm is 'true', then an interface or query should always expect a value for that property, and can validate against that expectation. If the termName is Taxon (a class) and isMandatoryTerm is 'true', then similarly the expectation will be that at least one populated Taxon object is linked to every ObjectGroup. If the isRepeatableTerm property is set to 'false', then the expectation will be that exactly one populated Taxon object is linked to every ObjectGroup and no more.
Examples	true false

ltc:isRepeatableTerm Property
Qualified Term	ltc:isRepeatableTerm
Label	Is Repeatable Term
Definition	A flag to designate whether multiple instances of the Latimer Core class or property defined in the termName property may be attached to a single ObjectGroup.
Notes	This property essentially defines whether the property or class is used for a 'tagging' approach (e.g. attaching multiple Taxon records to the same ObjectGroup to reflect the taxonomic scope, or a 'dimensional' approach (e.g. attaching a single GeologicalContext to an ObjectGroup, to show that it represents only objects from the Mesozoic). This has implications on how metrics may be handled, and more information is available in the non-normative guidance.
Examples	true false

ltc:termName Property
Qualified Term	ltc:termName
Label	Term Name
Definition	The name of a class or property within the Latimer Core standard that is included in the LatimerCoreScheme.
