CKAN (group)

Note

This page is automatically generated from the source code, and is a bit rough. If you have trouble, check the source code for this type or post a message to the forum.

A CatalogGroup representing a collection of layers from a CKAN server.

Initialization File properties:

"type": "ckan"

_nameInCatalog

The name of the item to show in the catalog, if different from name. Default undefined. This property is observed.

_sourceInfoItemNames

The names of items in the CatalogMember's info array that contain details of the source of this CatalogMember's data. This should be overridden by children of this class.

allowEntireWfsServers

True to allow entire WFS servers (that is, WFS resources without a clearly-defined layer) to be added to the catalog; otherwise, false.

allowEntireWmsServers

True to allow entire WMS servers (that is, WMS resources without a clearly-defined layer) to be added to the catalog; otherwise, false.

blacklist

A hash of names of blacklisted groups and data sources. A group or data source that appears in this hash will not be shown to the user. In this hash, the keys should be the names of the groups and data sources to blacklist, and the values should be "true".

cacheDuration

The cache duration to use for proxied URLs for this catalog member. If undefined, proxied URLs are effectively cachable forever. The duration is expressed as a Varnish-like duration string, such as '1d' (one day) or '10000s' (ten thousand seconds).

customProperties

The dictionary of custom item properties.

dataCustodian

A description of the custodian of the data sources in this group. This property is an HTML string that must be sanitized before display to the user.

description

The description of the item.

filterByWmsGetCapabilities

A value indicating whether the CKAN datasets should be filtered by querying GetCapabilities from each referenced WMS server and excluding datasets not found therein.

filterQuery

The filter query to pass to CKAN when querying the available data sources and their groups. Each item in the array causes an independent request to the CKAN, and the results are concatenated. The search string is equivalent to what would be in the parameters segment of the url calling the CKAN search api. See the Solr documentation for information about filter queries. Each item can be either a URL-encoded string ("fq=res_format%3awms") or an object ({ fq: 'res_format:wms' }). The latter format is easier to work with. To get all the datasets with wms resources: [{ fq: 'res_format%3awms' }] To get all wms/WMS datasets in the Surface Water group: [{q: 'groups=Surface Water', fq: 'res_format:WMS' }] To get both wms and esri-mapService datasets: [{q: 'res_format:WMS'}, {q: 'res_format:"Esri REST"' }] To get all datasets with no filter, you can use [''] This property is required.

forceProxy

Gets or sets whether or not this member should be forced to use a proxy. This property is not observable.

groupBy

A value indicating how datasets should be grouped. Valid values are: * none - Datasets are put in a flat list; they are not grouped at all. * group - Datasets are grouped according to their CKAN group. Datasets that are not in any groups are put at the top level. * organization - Datasets are grouped by their CKAN organization. Datasets that are not associated with an organization are put at the top level.

hideSource

Indicates that the source of this data should be hidden from the UI (obviously this isn't super-secure as you can just look at the network requests).

id

An optional unique id for this member, that is stable across renames and moves. Use uniqueId to get the canonical unique id for this CatalogMember, which is present even if there is no id.

includeCsv

True to allow CSV resources to be added to the catalog; otherwise, false.

includeCzml

True to allow CZML resources to be added to the catalog; otherwise, false.

includeEsriFeatureServer

True to allow ESRI FeatureServer resources to be added to the catalog; otherwise, false.

includeEsriMapServer

True to allow ESRI MapServer resources to be added to the catalog; otherwise, false.

includeGeoJson

True to allow GeoJSON resources to be added to the catalog; otherwise, false.

includeKml

True to allow KML resources to be added to the catalog; otherwise, false.

includeWfs

True to allow WFS resources to be added to the catalog; otherwise, false.

includeWms

True to allow WMS resources to be added to the catalog; otherwise, false.

initialMessage

A message object that is presented to the user when an item or group is initially clicked The object is of the form {title:string, content:string, key: string, confirmation: boolean, confirmText: string, width: number, height: number}.

isHidden

A value indicating whether this item is hidden from the catalog. This property is observable.

isOpen

A value indicating whether the group is currently expanded and showing its children.

isPromoted

A value indicating whether this item is kept above other non-promoted items.

isUserSupplied

A value indicating whether this member was supplied by the user rather than loaded from one of the Terria's initSources. User-supplied members must be serialized completely when, for example, serializing enabled members for sharing.

isWaitingForDisclaimer

Whether this catalog member is waiting for a disclaimer to be accepted before showing itself.

itemProperties

A hash of properties that will be set on each child item. For example, { "treat404AsError": false }

minimumMaxScaleDenominator

The minimum MaxScaleDenominator that is allowed for a WMS dataset to be included in this CKAN group. If this property is undefined or if CkanCatalogGroup's filterByWmsGetCapabilities is false, no filtering based on MaxScaleDenominator is performed.

name

The name of the item.

nameInCatalog

The name of this catalog member in the catalog. By default this is just name, but can be overridden.

shortReport

A short report to show on the now viewing tab.

ungroupedTitle

A title for the group holding all items that don't have a group in CKAN. If the value is a blank string or undefined, these items will be left at the top level, not grouped.

url

The URL of the CKAN server.

useCombinationNameWhereMultipleResources

A value indicating whether each catalog item's name should be populated from individual resources and the CKAN dataset where the are multiple resources for a single dataset.

useResourceName

A value indicating whether each catalog item's name should be populated from individual resources instead of from the CKAN dataset.

wmsParameters

Any extra wms parameters that should be added to the wms query urls in this CKAN group. If this property is undefined then no extra parameters are added.
