[DG-BSC] Verifiable Claims and standardizing around distributed ledgers to reduce the need for federations

You might find the outlines below useful to explain where this might be
headed. I have no idea whether linked data is needed to get there but I do
share their interest in deprecating the role of federations as a way to
reduce the asymmetry of the current Internet as relates to individuals,
including licensed professionals.

To be more explicit about how I hope Verifiable Claims and distributed
ledgers will help, right now licensed professionals tend to link their
claims to an employer and the employer verifies the attribute, often
injecting other strategic interests into the process. This reduces the
autonomy of the licensed professional to a much larger extent than was the
case with paper-based systems. Since licensed professionals don't buy IT
directly, they have not seen the strategic reduction in their autonomy
until rather recently as the actual impact of massive institutional record
systems on the professional-individual relationship has begun to chafe.

The 2nd International Workshop on Linked Data and Distributed Ledgers.
A workshop of ESWC 2017, Portoroz, Slovenia, May 29th, 2017
(1st edition will be held in conjunction with WWW 2017 - Perth, Australia)

*Important Dates:*

   - *Submission deadline:* Friday March 10, 2017
   - *Notifications:* Friday March 31, 2017
   - *Camera-ready version:* Thursday April 13, 2017

Distributed Ledgers (DLs) have emerged as a novel way to manage and
exchange different types of digital assets among a large number of agents
operating in a decentralised way. Existing DL platforms are driven by use
cases from different user communities. Each community has its own
requirements regarding the level of decentralisation, privacy, and identity
management that the ledger would need to offer. To allow for these
developments to be applicable to a wider, and more
complex range of applications, they will need to be able to interoperate,
both with existing distributed systems and databases technologies, and
among each other. This has motivated researchers and practitioners to look
at approaches such as Linked Data, which relies on core Web principles and
standards such as URIs, HTTP, JSON-LD, RDF, and SPARQL.

We envision the workshop as a forum for researchers and practitioners from
Distributed Ledgers and Linked Data to come together to discuss common
challenges; propose solutions to shortcomings of existing architectures;
and identify synergies for joint initiatives. The ultimate goal is the
creation of a Web of Interoperable Ledgers.

The first edition of LD-DL will be held as part of WWW 2017 in Perth,

We invite original research submissions addressing any of the following two
broad themes:

Linked Data for Distributed Ledgers:

Vision, insight and research on 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:

Vision, insight and research on 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
