Pure JavaScript, pure Open Source library for building mapping sites.
MetaCarta Labs offers experimental tools that are not yet commercially supported, so they may disappear without warning or perform erratically. If something's not working, please try it again later.
MetaCarta Labs is strongly in support of RESTful technology around GIS. FeatureServer is a REST-based geographic feature storage engine, which includes relatively complete Atom Publishing Protocol support.
