Class: CitationModel

CitationModel()

A Citation Model represents a single Citation Object returned by the metrics-service. A citation model can alternatively be populated with a SolrResultsModel or a DataONEObjectModel, or an extension of either of those models. A Citation Model can represent a citation to a local MetacatUI object, or an external document or publication.

defaults :Object

The default Citation fields
Type:
  • Object
Properties:
Name Type Description
origin string text of authors who published the source dataset / document / article
originArray Array.<string> array of authors who published the source dataset / document / article. Same as origin, but split on commas and trimmed.
title string Title of the source dataset / document / article
year_of_publishing number Year in which the source dataset / document / article was published
source_url string URL to the source dataset / document / article. This is usually an external publication that cites one or more DataONE datasets.
source_id string Unique identifier for the source dataset / document / article that cited the target dataset. This is usually an external publication that cites one or more DataONE datasets.
target_id string Unique identifier to the target DATAONE dataset. This is the dataset that was cited by the "source" document.
publisher string Publisher for the source dataset / document / article
journal string The journal where the the document was published
volume number | string The volume of the journal where the document was published
page number The page of the journal where the document was published
citationMetadata Citations When this Citation Model refers to an external document, citationMetadata is a collection of DataONE datasets that the external document cites. This info is retrieved by the metrics service, then parsed and stored as a collection of Citation Models. This attribute is used in the Portals view, for example, where we display a list of external publications that cite the portal data. In this case, each publication's citationMetadata is the list of local MetacatUI data packages cited in the publication.
sourceModel Backbone.Model The model to use to populate this citation model. This can be a SolrResultsModel, a DataONEObjectModel, or an extension of either of those models. Do not set this attribute directly. Instead, use the setSourceModel() method.
pid string The pid or unique identifier of the object being cited.
seriesId string The seriesId of the object being cited
view_url string For citations that are in the local MetacatUI repository, this is the URL to the metadata view page for the object being cited.
pid_url string If the pid is a DOI, then this is the URL to the DOI landing page for the object being cited. This will automatically be set when the pid attribute is set.
seriesId_url string If the seriesId is a DOI, then this is the URL to the DOI landing page for the object being cited. This will automatically be set when the seriesId attribute is set.

populateFromModel(model)

Do not call this method directly. Instead, call setSourceModel(), which will update listeners and then call this method. This method will populate this citation model's attributes from another model, such as a SolrResult model or a DataONEObject model. This will reset and overwrite any existing attributes on this model.
Parameters:
Name Type Description
model Backbone.Model The model to populate from, accepts SolrResult or a model that is a DataONEObject or an extended DataONEObject. If no model is passed, then the model will be reset to the default attributes.

set(key, val, options)

Override the default Backbone.Model.set() method to format the title, page, and volume attributes before setting them, and ensure that attributes that are different formats of the same value are in sync, including: origin and originArray; pid and pid_url; seriesId and seriesId_url. This method will prevent the sourceModel attribute from being set here.
