Vocabulary

This defined vocabulary aims at providing all essential terms to describe datasets of functional trait measurements and facts for ecological research.

The list of terms is ordered into a core section with essential columns for trait data, extensions which are allowing to provide additional layers of information, as well as a vocabulary for metadata information of particular importance for trait data. Another section provides defined terms for trait definitions to be included in the metadata or published along with the dataset.

We provide four extensions of the vocabulary, that allow for additional information on the trait measurement.

This glossary of terms is available as

The rationale for developing the Ecological Trait-data standard has been cast in a paper that is available as pre-print:

Schneider, F.D., Jochum, M., Le Provost, G., Ostrowski, A., Penone, C., Fichtmüller, D., Gossner, M.M., Güntsch, A., König-Ries, B., Manning, P. and Simons, N.K. (2018) Towards an Ecological Trait-data Standard, biorxiv.org DOI: 10.1101/328302

The vocabulary builds on the Darwin Core Standard (DWC; Darwin Core Terms and extensions; these are referenced in field ‘Refines’; the full Darwin Core Standard can be found here: http://rs.tdwg.org/dwc/terms/index.htm). Note that the documentation page resolves deprecated terms to the term that replaces them in definition, unless they differ in definition. Via API access or in the OWL and CSV file, the definition is accessible for each deprecated term.

Core traitdata terms

For the essential primary data (trait value, taxon assignment, trait name), it is recommended to report the original naming and value scheme as used by the data provider. However, to ensure compatibility with other datasets, the original data provider’s information should be duplicated into standardized columns indexed by appending Std to the column name. This ensures compatibility on the provider’s side and transparency for data users on the reported measurements and facts, and enables checking for inconsistencies and misspellings in the complete dataset provided by the author. If provided, the standardized fields allow merging heterogeneous data sources into a single table to perform further analyses. This practice of double bookkeeping of trait data has successfully established for the TRY database on plant traits, for instance (Kattge et al. 2011. TRY – a global database of plant traits. Global Change Biology, 17, 2905–2935).

By linking to (public) ontologies via the field taxonID, further taxonomic information can be extracted for analysis. Alternatively, taxonID may also link to an accompanying datasheet that contains information on the taxonomic resolution or specification of the observation.

Similarly, linking to published trait definitions in public thesauri or ontologies via the field traitID allows an unambiguous interpretation of the trait measurement. If no online ontology is available, an accompanying data table should specify the trait definitions by making use of terms provided in the section ‘Traitlist’ below.

occurrenceID
Definition An identifier for the Occurrence (as opposed to a particular digital record of the occurrence). In the absence of a persistent global unique identifier, construct one from a combination of identifiers in the record that will most closely make the occurrenceID globally unique.
Comment For a specimen in the absence of a bona fide global unique identifier, for example, use the form: “urn:catalog:[institutionCode]:[collectionCode]:[catalogNumber]. Examples:”urn:lsid:nhm.ku.edu:Herps:32“,”urn:catalog:FMNH:Mammal:145732“. For discussion see http://terms.tdwg.org/wiki/dwc:occurrenceID. This is important for the analysis of co-variation of morphometric data or intraspecific variation. It also couples multiple measurements on a single specimen, which also could be a leaf or a single bone without an assignment to an individual organism. If available, upload related dataset to describe specimens more precisely, e.g. environmental parameters or identity related information.

Metadata vocabulary

To describe trait-datasets unambiguously, we suggest the following terms to be used in the metadata accompanying the publication of trait-data.

To retain the rights of the original data contributor use author. Data owner rightsHolder states the person or organization that owns or manages the rights to the data; bibliographicCitation states a bibliographic reference which should be cited when the data is used; and license specifies under which terms and conditions the data can be used, re-used and/or published. Since trait data are of great use for synthesis studies, information about how the data may be distributed, re-used and attributed to are of particular importance for trait datasets. Most researchers encourage re-use of their published datasets while making sure they are sufficiently credited. The use of permissive licenses for traitdata publications, such as Creative Commons Attribution or Creative Commons Zero/Public Domain release, has been established as the gold standard.

When combining datasets from different sources, datasetID may keep the reference to an external data sheet specifying the metadata. Alternatively, the terms of this section can be added as columns to the dataset to maintain important information about authorship and terms of use at the measurement level.

Terms for trait definitions

To cope with the variety of data types, trait-data should make use of globally valid and unambiguous trait definitions from public ontologies or thesauri, by providing their URIs in the field traitID. Using this standardized terminology will facilitate merging trait definitions from multiple sources.

If no published trait definition is available that can be referenced, trait-datasets should be accompanied by a dataset-specific glossary of traits that would provide a definition specific to the study context. To be unambiguous, this list should be defining terms based on other well-defined terms from semantic ontologies, e.g. for units or higher hierarchical terms from trait ontologies (using broaderTerm). Also refer to well-defined terms of other ontologies that describe standard units, morphological body parts, protein characteristics (Protein Ontology) or chemical terms (e.g. the ChEBI, http://www.obofoundry.org/ontology/chebi.html).

The following vocabulary helps to provide trait definitions as a separate data table or within the metadata object along with the publication of the trait dataset.

Categorical traits should define a constrained set of factor levels, such as sex differences in wing morphology (both sexes winged, both sexes unwinged, only males winged, only females winged) or unconstrained entries such as color. Ordinal categorical traits may be better encoded as integer values, e.g. a logical sequence as in the case of life stages or hibernation stages, or habitat preference traits such as horizontal stratum use.

Extension: Taxon

This section provides terms to specify taxonomic resolution and hierarchical depth of the observed measurement or fact.

Especially when only providing a ‘scientificName’ an entry in kingdom is recommended to identify homonyms. Additionally, class, order, phylum, family and genus are variables to filter the dataset by. The entry taxonRank should be specified to name the hierarchical level to which the observation applies, i.e. if data were measured on a verified instance of species “Agrotis exclamationis”, taxonRank would be “species”. If the reported fact was generali

If the dataset provides a URI within taxonID that maps to a taxonomic online reference or lookup table of an unambiguous and commonly accepted or verified species name, most of these information are redundant. They should be provided nonetheless to enable sorting and analysis by higher hierarchical levels.

Extension: Measurement or Fact

This section provides additional information about a reported measurement or fact and in most cases can easily be included as extra columns to the core dataset.

As a high-level discrimination of the source of the measurement or fact, the Darwin Core Term basisOfRecord takes an entry about the type of trait data recorded: Were they taken by own measurement (distinguish “LivingSpecimen”, “PreservedSpecimen”, “FossilSpecimen”) or taken from literature (“literatureData”), from an existing trait database (“traitDatabase”), or is it expert knowledge (“expertKnowledge”). It is highly recommended to provide further detail about the source in the column basisOfRecordDescription.

To keep track of potential sources of noise or bias in measured data, the method of measurement (measurementMethod), the person conducting the measurement (measurementDeterminedBy), and the date at which the measurement was obtained (measurementDeterminedDate) are recorded. Authors would often report aggregate data of repeated or pooled measurements, e.g. by weighing multiple individuals simultaneously and calculating an average. In these cases, recording the number of individuals (individualCount) along with a dispersion measure (e.g. variance or standard deviation, dispersion) or range of values (e.g. min and max of values observed in the field measurementValueMin, measurementValueMax) is adviced. The field statisticalMethod names the method for data aggregation (e.g. mean or median) as well as the variation or range (e.g. reporting variance or standard deviation).

For data not obtained from own measurement, the field references provides a precise reference to the source of data (e.g. a book or existing database) or the authority of expert knowledge. For literature data, the original source might report trait values on the family or genus level, but the dataset author infers and reports the trait data at species level (e.g. if the entire genus reportedly shares the same trait value). To preserve this information, the column measurementResolution should report the taxon rank for which the reported value was originally assessed.

Extension: Occurrence

This category of terms contains further information about the individual specimen or occurrence that has been observed and measured. Especially for analyses of intra-specific trait variation, this composes valuable data. It also helps tracking the methodology and primary source of the data and keep the reference to the actual specimen (e.g. for museum collections or related data analysis).

For both literature and measured data, trait values may be recorded for different sub-categories of individuals of a taxon to capture polymorphisms, for instance differentiated by sex or life stage. The template provides the fields sex, lifeStage, age, and morphotype for this distinction.

Sampling may be further specified using a unique identifier for the sampling event (eventID) which references to an external dataset. The record of a samplingProtocol may capture bias in samling methods. Further procedures and methods of preservation should be reported in preparations.

Seasonal variation of traits may be recorded by assigning a date and time of sampling to the occurrence, using the fields year, month and day, depending on resolution. Further field definitions of the Darwin Core Standard can be applied instead, to refer to a geological stratum, for instance.

To capture geographic variation of traits, a set of fields for georeferencing can put the observation into spatial and ecological context (habitat, decimalLongitude, decimalLatitude, elevation, geodeticDatum, verbatimLocality, country, countryCode). The field locationID may be used to reference the occurrence to a dataset-specific or global identifier. This allows the trait data to double as observation data, e.g. for upload to the GBIF database.

For most trait data compiled from literature or expert knowledge, the level of information on an ‘occurrence’ would not apply, since no specific individual has been observed. In this case, the field ‘occurrenceID’ should be left blank in the core data. In cases where different aggregate ranges or averages are reported for male and female individuals, the columns sex or developmental stage may be used without the reference to an occurrence ID.

sex

Extension: Biodiversity Exploratories

This section records location in the context of the Biodiversity Exploratories project (www.biodiversity-exploratories.de). The field OriginExploratories flags trait measurements originating from samples in the project context. Exploratory and ExploType allow to place the sample within a region or a landscape type (Grassland or Forest). From ExploratotriesPlotID a detailled georeference can be inferred. Additional spatial resolution, e.g. on subplots, may be provided in locationID of the Occurence extension.

Trait data uploaded to the Biodiversity Exploratories Information System (BExIS) should use the vocabulary in a single-file longtable format (no DwC-Archives supported).
