Model for Quill Embeds that have to be indexed and may reference to some same source. A Module base class is also provided to implement and model blots with diferent HTML content (e.g., headers, images, tables, figures, formulas)

It makes an imaginary two dimensional matrix where:

• one dimesion i represents the diferents Sources of a Document (DSM/DocumentSourcesModel.js)
• other dimension j represents the diferents References in the document to the same Source. (DSM/SourceReferencesModel.js)
• Each Reference (DSM/Referenece.js) is an interface to a SourceBlot (quill/blots/source.js) in Quills document. Each SourceBlot is a Quill's interface to a HTML node.
• Each Model of Sources, model certain SourcesTypes (DSM/SourceTypes.js). For each source type, each source is identified by an arbitrary string key thant could be anything as a tipical integer ID, or some Tag (e.g., surname2020).

It keeps the i dimension ordered in accordance to the position of the first ocurrence of a Reference of such source. The first sources in appear, are ordered before the others.

It is implemented as a Quill module. Citations is a basic module that can be easily extended to make more complex types of sources (images, tables, links, headers, anything that could be of interest in to be indexed).

The implementation of Citation is very basic and actually it is meant to be used by the module configuration of quill.

For example:

import {SourceTypes} from 'dsm/DSM/SourceTypes';
import Quill from 'quill'

import SourceBlot from 'dsm/quill/blots/source';
import Citations from 'dsm/quill/modules/Citations'

// Blot para referencias
Quill.register(SourceBlot);
// Módulo de citaciones
Quill.register('modules/citation', Citations);



const quillOptions = {
    placeholder: 'Make something epic..',
    theme: 'bubble',
    modules: {
        citation: {
            type: SourceTypes.CITATION_DOCUMENT,
            class: 'citation',
            handlers: {
                create: function (node, data, controller) {
                    node.setAttribute('title', data.key)
                }
            }
        }
    },
}
                    
const quill = new Quill(quillContainer, quillOptions);

// Gets the module
const citations = quill.getModule('citation');

// Ads a citation to the source identified with the 'gus2020' key, 
// in the current location of the cursor
citations.put('gus2020');
