onSuccessfulSave(modelopt, responseopt, xhropt)

This function is executed when the XHR that saves this DataONEObject has successfully completed. It can be called directly if a DataONEObject is saved without directly using the DataONEObject.save() function.
Parameters:

Overrides:
Source:

removeWhiteSpaceFromSolrFields(json)

Removes white space from string values returned by Solr when the white space causes issues. For now this only effects the `resourceMap` field, which will index new line characters and spaces when the RDF XML has those in the `identifier` XML element content. This was causing bugs where DataONEObject models were created with `id`s with new line and white space characters (e.g. `\n urn:uuid:1234...`)
Parameters:
Name Type Description
json object The Solr document as a JS Object, which will be directly altered
Inherited From:
Source:

Inherited From:
Source:

setProvClass(className)

Set the DataONE ProvONE provenance class param className - the shortened form of the actual classname value. The shortname will be appened to the ProvONE namespace, for example, the className "program" will result in the final class name "http://purl.dataone.org/provone/2015/01/15/ontology#Program" see https://github.com/DataONEorg/sem-prov-ontologies/blob/master/provenance/ProvONE/v1/provone.html

updateID(id)

Update identifiers for this object
Parameters:

Note that this method caches the objects attributes prior to updating so this.resetID() can be called in case of a failure state. Also note that this method won't run if theh oldPid attribute is set. This enables knowing before this.save is called what the next PID will be such as the case where we want to update a matching EML entity when replacing files.
