Hi,
I don't usually write to this list, and have no idea what SILK is about
(Sorry SILK people!), but I found the below email to be incredibly harsh.
Look at the git history of the project (which was 1 click way from the email
I am referring to below!), it does seem to be in active development, with a
number of committers:
http://www.assembla.com/code/silk/git/node/logs?page=1 (apache license 2.0)
And the page DOES seem to reflect this:
http://www4.wiwiss.fu-berlin.de/bizer/silk/
Perhaps there was a bug in the HTML(?), I don't know - but I would give
people the benefit of the doubt before pointing fingers in public. I do
think a personal email to Robert would probably have sufficed, but perhaps I
am just that way inclined.
I have recently unsubscribed from a few of the SW based mailing lists
because of trolling and people being incredibly rude - and I hope I don't
have to remove myself from any others. The Semantic Web community is full of
a great number of nice, helpful, intelligent people, and I find it a
pleasure and an honour to be involved with this international community of
awesome.... Lots of people put lots of time and effort into writing open
specs and open-source code - and i don't see how finger pointing helps
anyone!

thanks lot for the update, I look forward to be trying it out
I see from this page
http://www4.wiwiss.fu-berlin.de/bizer/silk/
that SILK V 2.4, announced on this list today was actually released
last year: See the snippet below
2010-06-01: Version 2.4 released including the new Silk Workbench, a
web application which guides the user through the process of
interlinking different data sources.
I also seem to understand from the project page that much of LOD2
software are tools developed in previous years (ie, nothing new!)
Am I reading something wrong?
In the past decade or so, millions of euros of tax payers money have
been paid for projects for which the codebase had already been
developed, either by funded projects from prior calls( ie, for which
the tax payer had already paid ) or by other companies.
In essence, as it has been already pointed out, the public has been
paying for the same semantic web tools to be rebranded over and over,
and each time it has costed lots of public money, and each time it has
not delivered the semantic web functionality the public is waiting for
(ie, a useable web based application layer)
Since LOD2 has become a funded EU project in September 2010, I would
be grateful if you could explain what part of the tool/functionality
has been developed after September 2010, and for what part of this
development is the public funding being used for
Thanks a lot in advance

Hi all,
we are happy to announce version 2.4 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 datasets as well
as by Linked Data consumers to augment Web data with additional RDF
links.
Link specifications can either be written manually or developed using
the new Silk Workbench. The Silk Workbench, is a web application which
guides the user through the process of interlinking different data
sources. It’s being shipped with the 2.4 version of Silk.
The Silk Workbench offers the following features:
- It enables the user to manage different sets of data sources and
linking tasks.
- It offers a graphical editor which enables the user to easily create
and edit link specifications.
- As finding a good linking heuristics is usually an iterative
process, the Silk Workbench makes it possible for the user to quickly
evaluate the links which are generated by the current link
specification.
- It allows the user to create and edit a set of reference links used
to evaluate the current link specification.
The Silk Link Discovery Framework includes three applications to
execute the link specifications 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 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.
3. Silk MapReduce is used to generate RDF links between datasets 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.
More information about the Silk framework, the Silk Link Specification
Language, 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:
http://www4.wiwiss.fu-berlin.de/bizer/silk/
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).
Thanks to Christian Becker, Michal Murawicki and Andrea Matteini for
contributing to the Silk Workbench.
