register datasets with ODIS (using JSON-LD)

[bbest]

From @evsatt:

I tried creating a record -- here. It looks like I might need support in creating the json-ld (step 3 here). I welcome thoughts on this -- figure it might be worth trying to go through this and having specific questions when we meet with the technical folks next.

JSON-LD in ERDDAP

Previously I responded:

Looking good! Since this record is pointing to an ERDDAP dataset, I thought we heard that a JSON-LD record was already created by any dataset served by ERDDAP, OBIS or EDI. However, I'm having trouble finding it for ERDDAP (only a mention here). I'll research this further.

And now I'm seeing the JSON-LD embedded in the ERDDAP page, when you View Source:

https://upwell.pfeg.noaa.gov/erddap/info/siocalcofiHydroBottle/index.html:

<script type="application/ld+json">

  "@context": "http://schema.org",

  ...

    "description": "Original provider:\nPRBO Conservation Science\n\nDataset credits:\nThe projects were conducted under the grants awarded to the following \norganizations and their scientists.\n\nThe principle investigators of the CalCOFI part of this dataset are\n(in the chronological order from 1987 to 2006):\nRichard Veit and John McGowan, Scripps Institution of Oceanography (1987-1994)\nDavid Hyrenbach, Scripps Institution of Oceanography (1994-2000)\nBill Sydeman, PRBO Conservation Science (2000-2006)\n\nThe principle investigators of the Rockfish part of this dataset is\nBill Sydeman, PRBO Conservation Science (1996-2006)\n\n# the affiliations are the ones they belonged to at the time of the surveys.\n\nThe data were contributed by PRBO Conservation Science.\nThese two projects are on going. See [Supplemental information] for the \ninformation on the PIs and organizations in recent years.\n\nAbstract:\nThis dataset contains observation data of marine birds and mammals from California Cooperative Oceanic Fisheries Investigations (CalCOFI) from 1987-2006 and Rockfish cruises along the California coast from 1996-2006 by National Marine Fisheries Service (NMFS).\n\nData were collected aboard research vessels using standardized marine bird and mammal survey techniques (Tasker et al. 1984, Buckland et al. 1993). Marine birds \nand mammals were observed in a 90-degree arc from the bow to one side of the ship out to 300m. Counts are summarized by species and behavior along the transects in 3 km bins. Data span years 1987 - 2006.\n\nPurpose:\nRelating changing ocean productivity patterns and upper-trophic predator (seabirds and marine mammals) distributions to the underlying physical oceanographic variability enhances our understanding of the ecological context of the CalCOFI and NMFS database, thereby aiding in the interpretation of large-scale hydrographic and ocean productivity patterns.  An inter-disciplinary, ecosystem-level perspective will provide new insight into offshore California wildlife habitat associations and how apex marine organisms (including fish with diets similar to seabirds and/or mammals) respond to differences in ocean climate, productivity, and water mass properties, information needed to manage fisheries and wildlife under changing ocean conditions.\n\nSupplemental information:\n[2020-09-30] The following invalid species names were corrected according to the Integrated Taxonomic Information System (ITIS).\nBlack-footed Albatross: Diomedea nigripes (174516) =&gt; Phoebastria nigripes (554379)\nBonaparte's Gull: Larus philadelphia (176839) =&gt; Chroicocephalus philadelphia (824040)\nCaspian Tern: Sterna caspia (176924) =&gt; Hydroprogne caspia (176935)\nElegant Tern: Sterna elegans (176925) =&gt; Thalasseus elegans (176931)\nFranklin's Gull: Larus pipixcan (176838) =&gt; Leucophaeus pipixcan (824082)\nGreat Egret: Casmerodius albus (174810) =&gt; Ardea alba (554135)\nLaughing Gull: Larus atricilla (176837) =&gt; Leucophaeus atricilla (824079)\nLaysan Albatross: Diomedea immutabilis (174517) =&gt; Phoebastria immutabilis (554378)\nLeast Tern: Sterna antillarum (176923) =&gt; Sternula antillarum (824127)\nRed Phalarope: Phalaropus fulicaria (554376) =&gt; Phalaropus fulicarius (176734)\nRoyal Tern: Sterna maxima (176922) =&gt; Thalasseus maximus (824142)\nSouth Polar Skua: Catharacta maccormicki (176801) =&gt; Stercorarius maccormicki (660062)\nWillet: Catoptrophorus semipalmatus (176638) =&gt; Tringa semipalmata (824147)\nParula americana (178868) =&gt; Setophaga americana (950033)\nDendroica petechia T(178878) =&gt; Setophaga petechia (950039)\nDendroica townsendi (178897) =&gt; Setophaga townsendi (950058)\nDendroica occidentalis (178902) =&gt; Setophaga occidentalis (950059)\nDendroica coronata (178891) =&gt; Setophaga coronata (950046)\nWilsonia pusilla (178973) =&gt; Cardellina pusilla (950080)\n\n[UPDATE 2013-03-25] The following species codes had been associated with invalid species names. These were corrected to valid species names.\nWWSC White-Winged Scoter =&gt; Melanitta fusca deglandi\nSTAL Short-Tailed Albatross =&gt; Phoebastria albatrus\nLAAL Laysan Albatross =&gt; Diomedea immutabilis\nLETU Leatherback Turtle =&gt; Dermochelys coriacea\nThese data are publicly available without restriction.

The location is represented at \nthe middle of the bin. Length may be less at the end of a transect, and width \nmay be less depending on the weather.\nEach bin is temporally about 10 minutes in duration (depending on ship speed).\n\nTracklines on this map represent on-effort only. Off-effort tracks may be obtained \nfrom the data provider.",

  "description": "The fish larvae (ichthyoplankton) survey is conducted through the\n    California Cooperative Fisheries Investigations program (CALCOFI,\n    http://www.calcofi.org/). These data are a time series of fish\n    larvae counts (or density, as number per 10 square meter of ocean\n    surface) collected in the area of the California Current between San\n    Diego and Avila Beach, California. Original data were filtered to\n    facilitate consistent comparisons over time and space.\n  \n      \n    The original CalCOFI fish larvae count data is available from the\n    CoastWatch West Coast Regional Node (WCRN) at NOAA\u2019s Pacific\n    Fisheries Environmental Laboratory,\n    http://coastwatch.pfeg.noaa.gov/erddap/tabledap/index.html. The\n    dataset presented here is an aggregation of 31 data files,\n    originally divided alphabetically by taxon (named \u201cCalCOFI Larvae\n    Counts, Scientific Names * to *\u201d). The data were filtered to include\n    only the 66 core stations with a maximum of 1 cruise per season.\n    These 66 core stations have been most frequently sampled in the past\n    and sampling is ongoing.\n  \n      \n    CalCOFI sampling began in 1949. However, the dataset presented here\n    begins in 1966 to include only samples that were analyzed with\n    techniques that apply the most current and accurate identification\n    of larvae to the species level. As the backlog of samples (i.e.,\n    before 1966) is re-examined, this dataset will be augmented with\n    that additional, earlier data.",

Google Dataset Search

It's also very interesting to find 71 datasets in Google's Dataset Search that combs the entire internet for these JSON-LDs.

Institute identifier? OceanExpert or ROR

OceanExpert

The recommendation from OBIS has been to use identifiers in OceanExpert for people and institutions.

I don't see an institute for CalCOFI when I search "calcofi" in OceanExpert.org, but I do see:

• expert Dr Erin SATTERTHWAITE
• institute Scripps Institution of Oceanography

Research Organization Registry (ROR)

Whereas OceanExpert is marine focused, GBIF and NOAA are embracing the newer global Research Organization Registry (ROR) at ROR.org.

For instance, see parent-child relationships:

• National Oceanic and Atmospheric Administration
  • NOAA National Ocean Service
    • NOAA Integrated Ocean Observing System

I learned about this through the MBON DMAC group:

• August IOOS DMAC Tech Webinar – 2024-08-29 - YouTube

And querying for "calcofi" on Google Dataset Search, there are:

• 71 datasets on Sep 11; vs
• 77 datasets for today Oct 2:

ODIS Catalogue

But only 6 datasets show on https://catalogue.odis.org/search

Here are the existing dataset repositories that "should" be generating JSON-LD already:

Dataset Repositories with CalCOFI Datasets

1. ERDDAP (n=21 today)

Gridded or tabular data, including oceanographic data. (Other ERDDAP servers exist.)

• ERDDAP - Search
  

2. OBIS (n=5 today)

Biogeographic data as DarwinCore

• OBIS - the Ocean Biodiversity Information System
  

3. EDI (n=3 today)

Full dataset record with flexible dataset structure. Part of DataOne network.

• Environmental Data Initiative
