de.fuberlin.wiwiss.d2rq.map.DownloadMap

public class DownloadMap
extends ResourceMap

A d2rq:DownloadMap instance. This is a d2rq:ResourceMap that must produce URIs, can refer to a d2rq:ClassMap to provide further relation elements (joins, aliases, conditions), and additionally has a d2rq:mediaType and d2rq:contentColumn. Results can be retrieved via getContentDownloadColumn(), getMediaTypeValueMaker() (for the media type value make), ResourceMap.nodeMaker() (for the URI spec), and getRelation().
