Hi all,

we are happy to announce version 2.2 of the Silk - Link Discovery Framework
for the Web of Data.

The central idea of the Web of Data is to interlink data items using RDF
links. However, in practice most data sources are not sufficiently
interlinked with related data sources. The Silk Link Discovery Framework
addresses this problem by providing tools to generate links between data
items based on user-provided link specifications. It can be used by data
publishers to generate links between data sets as well as by Linked Data
consumers to augment Web data with additional RDF links.

The new Silk 2.2 framework is now provided in three different variants which
address different use cases:
1. Silk Single Machine is used to generate RDF links on a single machine.
The datasets that should be interlinked can either reside on the same
machine or on remote machines which are accessed via the SPARQL protocol.
Silk Single Machine provides multithreading and caching. In addition, the
performance can be further enhanced using an optional blocking feature.
2. Silk MapReduce is used to generate RDF links between data sets using a
cluster of multiple machines. Silk MapReduce is based on Hadoop and can for
instance be run on Amazon Elastic MapReduce. Silk MapReduce enables Silk to
scale out to very big datasets by distributing the link generation to
multiple machines.
3. Silk Server can be used as an identity resolution component within
applications that consume Linked Data from the Web. Silk Server provides an
HTTP API for matching instances from an incoming stream of RDF data while
keeping track of known entities. It can be used for instance together with a
Linked Data crawler to populate a local duplicate-free cache with data from
the Web.

More information about the Silk framework, the Silk-LSL language
specification, as well as several examples that demonstrate how Silk is used
to set links between different data sources in the LOD cloud is found at

The Silk framework is provided under the terms of the Apache License,
Version 2.0 and can be downloaded from

The development of Silk was supported by Vulcan Inc. as part of its Project
Halo (www.projecthalo.com) and by the EU FP7 project LOD2 - Creating
Knowledge out of Interlinked Data (http://lod2.eu/, Ref. No. 257943).

Happy linking,
