PIOTRe-web

PIOTRe-web is a frontend for PIOTRe with the goal of making it effortless to add a data source, create a mapping, build an app on top of it and publish the metadata.

PIOTRe is a Personal IoT Repository based on sparql2sql, sparql2stream and sparql2fed technologies. The name PIOTRe is also derived from the name Peter meaning "stone" or "rock" and is the foundation for applications built on interoperable and efficient database technology on lightweight IoT devices.

PIOTRe essentially consists of a sink for IoT data streams which flows to an events stream and a historical store and allows applications to be built on top with any programming language and framework. Historical data can be queried via a HTTP SPARQL endpoint while queries on streaming data can be registered most efficiently via the underlying ZeroMQ sockets by publishing streaming SPARQL query to a broker.

PIOTRe-web has a WYSIWYG editor for mappings in S2SML making it easy to create mappings which enhance interoperability with other PIOTRe and semantic web systems.

Most information about sparql2sql can be found on the wiki. This includes a reference for the S2SML language for sparql2sql mappings, benchmarks, implementation of the swappable BGP resolution interface, etc.
