GISIN Data Model Concepts Enabling Invasive Species Data Interchange GISIN technical team GISIN Training
Protocols • Protocol = Agreed upon language for data exchange • File formats, HTTP, KML • Dictates what can and cannot be exchagned • Types of protocols • DarwinCore: Loose • Country: United States, US, Estados Unidos, etc. • GISIN: “tighter” • UN Country codes
GISIN Protocol • Based on DarwinCore • Added concepts for invasive species • Provided controlled vocabularies where possible and needed • Data Models • Occurrences • SpeciesStatus • SpeciesResourceURLs
GISIN data models • Data model = data type of interest • Six data models • Three implemented • Species Resource URL • Species status • Occurrence • Three defined, not implemented • Management status • Impact status • Dispersal status • See the GISIN protocol for more information http://www.gisin.org/cwis438/websites/GISINDirectory/Tech/Protocol_Home.php
Some Definitions • Data Models: Type of data • Concepts • Fields • Parameters • Data types: • String: Names, descriptions • Enumerated: Yes/No, Indigenous/Exotic • Date: “2010-11-20” • Integer: Number of records to return • Floating Point: Longitude/Latitude
Data model concepts • Concepts = elements within data model • Common and data model specific • Required and optional • Free form and controlled vocabulary • Used standards where exist
Enumerated Controlled Vocabularies Allows interchange of data at different levels of detail Do not capture all the detail of each provider Intended to be mutually exclusive
Common Field Concepts • Descriptive • citation • memo • language (r) • Species • scientificName (R) • kingdom (R) • globalUniqueIdentifier • Dates • modified • endValidDate • startValidDate • Location • countryCode • stateProvince • county • localityName • localityType • locationStandard • locationValue
GUIDs • Global unique identifier • Will accept existing GUIDs, if provided • If not provided, recommend DwC-recommended standard and authority for persistent and resolvable GUIDs • www.gisin.org/guid will be the authority for now. • GUID permalink gisin.org/guid/[InstitutionCode]/[CollectionCode]/[CatalogNumber] Example: gisin.org/guid/niiss/godm/34654
Descriptive Concepts • Language • Required if any text is provided • Memo • Additional information from providers • Citation • Appropriate citation for each record • Must be maintained as data is repeated (retain previous provider citation) • GUIDs also helpful for this Available for all data models.
Species (Required - all) • Scientific Name • Specific epithet for the species • Prefer “Genus species” without author • “Bromus tectorum” • “Tamarix” • Kingdom (enumerated) • Required to remove ambiguity • Can be set for an entire file
Date • Date format must be: YYYY-MM-DD • Several date fields • Specify temporal precision • Year, month, or day • Start and end date can be the same
Location • One required by: • SpeciesStatus • Occurrence • 3 Methods of specifying location in use: • Latitude/Longitude (Occurrence only) • Locality: An enumerated type with a name • Location: an enumerated standard with a code
Locality • countryCode • Standard: Country code (ISO 3166) • stateProvince • Text in country’s primary language • county • Text in country’s primary language • Locality • localityType (enumerated): Waterbody, Locality (city), Island, etc. • localityName: Name of the area
Location • locationStandad: • USA_FIPS, USA_HUC, AR_PostalCode • locationValue: • Varies with standard Contact us about adding additional types or standards.
Latitude/Longitude • Required: • Decimal Latitude: 40.123 • Decimal Longitude: -105.23 • Optional: • geodeticDatum*: WGS84, HARN • coordinateUncertaintyInMeters • georeferenceProtocol (enumerated) *Datum should be required
Occurrences • Required Concepts: • scientificName • kingdom • Any type of location • Coordinates, Locality, or Location • Optional: • startCollectionDate • endCollectionDate • collectionDatePrecision • georeferenceProtocol • coordinateUncertaintyInMeters • Datum
SpeciesStatus • Required: • scientificName • kingdom • Locality or location Model specific • harmful • origin • presence • Optional: • startValidDate, • endValidDate • validDatePrecision • abundance • distribution • persistence • rateOfSpread • regulartoryListing • trend • publicationDate • publicationDatePrecision
Presence • Presence: • Unknown • Absent • SometimesPresent • Present • Reported
Harmful and Origin • Harmful: • Unknown • Yes • Potentially • No • Together: • Harmful = Yes, Origin = Exotic -> Invasive • Origin: • Unknown • Indigenous • Exotic
SpeciesResourceURL • Required: • scientificName, kingdom • resourceType: • Profile, Expert list, Image, Video, Reference list, Identification key, Risk assessment, Unknown • URL: • Full Uniform Resource Locator • http://www.issg.org/database/species/ecology.asp?si=1538&fr=1&sts=&lang=EN
