WEB FEATURE SERVICE (WFS)
Metadata for putting historical maps online22 July 2016
An open standard developed by the Open Geospatial Consortium allowing requests for geographical features across the web using platform-independent calls.
URL format request with response received as Geography Markup Language (GML) or Javascript Object Notation (JSON) format
For example, a WFS request...
http://geoserver.nls.uk/geodata/wfs?service=WFS&version=1.1.0&request=GetFeature&typename=nls:OS_6inch_UK_27700&outputFormat=text/javascript&format_options=callback:loadFeatures&srsname=EPSG:3857&cql_filter=INTERSECTS(the_geom,POINT(530232 179709))

VALUE OF GEOGRAPHIC COORDINATES FOR INDEXING
Metadata for putting historical maps online22 July 2016
● Allows flexible searching by text (place, postcode, county, etc.) and maps
● Allows multiple indexing by past/present geographies
● No need to be tied to fixed controlled vocabularies for geographic names
● Allows easier extension into other portals and harvesting sites
● Allows easier links from other websites and resources
● Allows creation of indexes of new names for new purposes
● Open, non-proprietory, and with complete institutional control over use
