Metadata resources / Add different types of document

[fxprunayre]

ISO19115-3 allows to document in more details a record (mainly by adding link to citation element).
Instead of placing all document in the distribution section, dispatch documentation based on the type of resources.

Main differences with ISO19139:

• Legend file (SLD, QML, LYR) are in portrayal section
• Feature catalogue referenced by URL are in content section
• DQ report are in standaloneQualityReport, report, additionalDocumentation

All types in the list are configurable:

{
// Optional / optGroup
group: 'onlineDiscover',
// Label
label: 'onlineDiscoverWMS',
// Optional / On select copy the label in desc field
copyLabel: 'desc',
// Optional / Icon
icon: 'fa gn-icon-onlinesrc',
// XSL process to run
process: 'onlinesrc-add',
// Optional / List of fields (URL only will be displayed if none)
fields: {
  'url': {},
  'protocol': {
    // Fixed value
    value: 'OGC:WMS', 
    // Hide field
    hidden: true},
  'name': {},
  'desc': {
    // Rename parameter for the XSL process
    param: 'myParam'},
  'function': {value: 'browsing', hidden: true}
}
}
