We invite original research submissions, demonstrations, industrial and vision papers addressing any of the following two broad themes:

Linked Data for Distributed Ledgers:

How to use Linked Data and Web technologies to enhance Distributed Ledgers, including but not limited to:

• Architectures and protocols for DL interoperability

• Architectures and protocols for interoperability between DLs and other Web components and architectures (non-ledger based web services, web databases, etc)

• Extensions of web data models and formats to accommodate Distributed Ledgers (JSON, HTTP, HTML, RDF, etc)

• Languages and query engines for Distributed Ledgers

• Privacy considerations of interoperating Distributed Ledgers

• Vocabularies and ontologies for describing DLs and Smart Contracts

• Semantification and linking of DL frameworks and their contents

• Storage, querying and updating RDF data inside Distributed Ledgers

• SPARQL extensions to use it as a Smart Contract language. Extensions to current Smart Contract languages to use semantic data.

Distributed Ledgers for Linked Data:

How to use DLs to enhance Linked Data and Web applications, including, but not limited to:

• Decentralisation and disintermediation of web-based architectures.

• Distributed management of identity and online identity.

• Distributed Ledger backing of general Linked Data processes: vocabulary

and dataset evolution, entity naming and re-naming, etc.

• DLs for Web and Linked Data provenance.

• DL-backing of Web signatures

• Digital rights management and enforcing
