In particular, this document proposes the following:\r \r Specific PubSub 1.0 extensions for CSW 2.0.2 and 3.0, leveraging on standard functionalities, data models, and semantics to enable sending notifications based on user-specified area of interest and/or keywords;\r \r A general, basic mechanism for enabling PubSub for the generic OGC Web Service over the existing request/reply OWS’s, i.e. usual requests as filters, usual responses as appropriate updates/data pushes, existing semantics and syntax expressiveness.\r \r This document is the result of activity performed within the Large-Scale Analytics (LSA) Thread of the OGC Testbed 12 Interoperability initiative, being identified as document deliverable A074 PubSub / Catalog Engineering Report. This document also captures lessons learnt from the implementation of component deliverable A016 CSW 2.0.2 with PubSub Core Support Server."""@en ; skos:notation "16-137r2" ; skos:prefLabel "Testbed-12 PubSub / Catalog Engineering Report"@en .
