'''Semantically-Interlinked Online Communities Project''' (SIOC ({{IPAc-en|ʃ|ɒ|k}} {{Respell|SHOK}}<ref>{{cite web|url=https://www.youtube.com/watch?v=Zh-4bRDmTd0 |archive-url=https://ghostarchive.org/varchive/youtube/20211213/Zh-4bRDmTd0 |archive-date=2021-12-13 |url-status=live|title=DataPortability and John Breslin|accessdate=18 January 2021}}{{cbignore}}</ref>)) is a [[Semantic Web]] technology. SIOC provides methods for interconnecting discussion methods such as blogs, forums and mailing lists to each other. It consists of the SIOC [[Ontology (computer science)|ontology]], an open-standard machine readable format for expressing the information contained both explicitly and implicitly in [[Internet]] discussion methods, of SIOC [[Metadata|metadata]] producers for a number of popular blogging platforms and content management systems, and of storage and browsing/searching systems for leveraging this SIOC data.

The SIOC vocabulary is based on [[Resource Description Framework|RDF]] and is defined using [[RDF Schema|RDFS]]. SIOC documents may use other existing ontologies to enrich the information described. Additional information about the creator of the post can be described using FOAF Vocabulary and the <code>foaf:maker</code> property. Rich content of the post (e.g., an [[HTML]] representation) can be described using the AtomOWL or [[RSS]] 1.0 Content module.

The SIOC project was started in 2004 by John Breslin and Uldis Bojars at [[Organization:Digital Enterprise Research Institute|DERI]], NUI Galway. In 2007, SIOC became a W3C Member Submission.<ref>{{cite news|url=https://www.advertiser.ie/galway/article/10727/obama-recovery-programme-using-technology-developed-at-nui-galway|title=Obama recovery programme using technology developed at NUI Galway|author=<!--not stated-->|date=2009-04-09|website=Galway Advertiser|access-date=2022-09-08}}</ref>
