Add COSCa as a Fraction Analyzed type

Hi,
NML would like to add cosca as Fraction Analyzed type
here is a brief description of a COSCa ball:
• A COSCa ball is a passive sampling device that allows us to obtain a composite sample for a given location.
• It is a 3D-printed plastic cage that houses absorbent material such as cotton, gauze, cheese cloth, etc.
• It is small enough to fit in the palm of your hands, but they can vary in size
• We mainly get grab samples (~400mL) from different locations which we use to conduct liquid and solid extractions
• The wastewater material extracted from COSCa balls is a much smaller volume and requires a slightly different extraction protocol.
• I have attached a paper that gives a much broader description
This is a category of collection in V2 (proposed). The category set is collectCat. I have added to that category set.
Within 'collectCat' we currently have the following categories (we haven't yet added all categories from other dictionaries, most notably CDC NWSS).
- Flow proportional 24hr sample
- Time proportional 24hr sample
- Representative grab sample
- Composite grab sample of 3
- Composite 3hr grab sample
- Composite 8hr grab sample
- Moore swab passive sample
- Surface swab
Also note, the current organization of sampling has three attributes:
siteType- Type of site or institution where the sample was taken. i.e. Airplane, Major sewer pipeline, Municipal wastewater treatment plant.sampleMaterial- Type of sample. i.e Primary clarifier effluent, Raw sewage at site, Holding tank.collection- Method used to collect the sample.
Fraction analysed is an attribute of a (sample) measurement, rather than a sample collection. Meaning, you can define the fractionAnalysed (solid, liquid, mixed) for several different sampleMaterials or collection.
@Bahamyirou can you attach the reference? We can add the reference to the parts list.
COSCa ball has been added to the dictionary as a category of collection, and the reference has been input as well. Thanks for flagging this, @Bahamyirou, I am closing this issue now.
