New Term - samplingEffortUnit

[tucotuco]

New term

• Submitter: Humboldt Extension Task Group

• Efficacy Justification (why is this term necessary?): Part of a package of terms in support of biological inventory data.

• Demand Justification (name at least two organizations that independently need this term): The Humboldt Extension Task Group proposing this term consists of numerous organizations.

• Stability Justification (what concerns are there that this might affect existing implementations?): None

• Implications for dwciri: namespace (does this change affect a dwciri term version)?: Needs ecoiri: equivalent. Proposed attributes of the new term:

• Term name (in lowerCamelCase for properties, UpperCamelCase for classes): samplingEffortUnit

• Term label (English, not normative): Sampling Effort Unit

• Organized in Class (e.g., Occurrence, Event, Location, Taxon): Event

• Definition of the term (normative): The units associated with the eco:samplingEffortValue.

• Usage comments (recommendations regarding content, etc., not normative): Recommended best practice is to use a controlled vocabulary.

• Examples (not normative): trap hours; person hours; trap days

• Refines (identifier of the broader term this term refines; normative): None

• Replaces (identifier of the existing term that would be deprecated and replaced by this term; normative): None

• ABCD 2.06 (XPATH of the equivalent term in ABCD or EFG; not normative): not in ABCD

Our ALA colleagues ask 'What happens if the samplingEffortValue and samplingEffortUnit require multiple values? Eg. “2 hours over 100m2”?'

Comment from YMG: Good point. I have a feeling that this is again related to eMoF https://github.com/gbif/rs.gbif.org/issues/103#issuecomment-1532983566 and https://github.com/gbif/rs.gbif.org/pull/102. Do dwc:sampleSizeValue and dwc:sampleSizeUnit have a similar challenge? If we are to provide recommendation for this, perhaps we should align the practice across other general terms like dwc:sampleSizeValue and dwc:sampleSizeUnit?

Comment from KI: As with other terms where this potential exists, we should recommend using pipe separators, |, where multiple values exist. It would also be prudent to include in the comments/examples that it is recommended that data providers populate dwc:samplingEffort (http://rs.tdwg.org/dwc/terms/samplingEffort) with verbatim sampling effort information.

Dear All,

Thanks Katie for all your efforts to move the ALA questions forward. This is making a big difference.

Regarding this issue separators would work but I would prefer dividing effort this option into three basic components: Space, time and sampling units each with a number and units

Some examples to spur the conversation

for pitfall traps 200 m, 5 days, 10 traps for bird survey 1 km, 30 minutes, 2 people for camera traps 1 hectare, 2 weeks, 14 cameras for eDNA 500 m, , 4 samples for plant survey 200 m transect | 10 m2 plots, 10 hours, 1 person for a drone 6 acres, 1 hour, 1 drone
