PROJECT OUTPUTS #3 - VETTING SERVICES

The ALA has a web service that accepts a POST request with a JSON body that contains the information to support a vetting.   

The URL for the service is: 
http://biocache.ala.org.au/ws/assertions/query/add  

Example JSON for the POST body:

Validating the supplied information

When the JSON body is invalid a HTTP Bad Request (400) will be returned.

When an invalid or no apiKey is provided a HTTP Forbidden (403) will be returned.

Otherwise the supplied information will be validated in 2 ways; first to ensure that the species name exists in the current system and finally ensuring that the area is a valid WKT format.  If either of these checks fail a HTTP Bad Request (400) is returned as the status with a message indicating the issue.

Insert/Update   

When inserting a new validation a first load date is populated.  This date is never updated.  The purpose of this date is to provide a context for “Historic” vettings.  In the future the ALA may provide additional QAs around records that appear in a “historic” region after the vetting first loaded date.

Each vetting that is posted to the web service will be stored in the database in raw JSON.  Other fields populated include a last modified date and query.  The query will be constructed using the species name and WKT for the area.   This query will be used to identify the records that are considered part of the vetting.

Deleting  

When a “delete” is issued against an existing vetting it is marked as deleted in the database.  It is not physically deleted until the action is filtered through to the ALA data.  A "deleted" assertion can NOT be resurrected.     

Applying Vettings to ALA Data

It is not yet known the exact process that will be used to apply the vettings to the ALA data.  It will be a batch process run nightly that updates a bunch of records based on the queries that were generated for each vetting. 

New/updated vettings that have not been pushed through to the ALA data will be applied to all records that satisfy the query.  Old vettings will be applied to records that have been inserted/modified since the previous batch process.
