[dotNetRDF-Develop] dotNetRDF 0.5.0 Beta and dotNetRDF Toolkit 0.3.0 Alpha Released

[Rob V. <rv...@do...>]

Hi All
We are please to announce that dotNetRDF 0.5.0 Beta has been released as 
well as the 0.3.0 Alpha release of the associated dotNetRDF Toolkit.  You 
can get the latest library from [1] and latest toolkit from [2]
The latest release of the library brings the following new features and 
improvements:Bug fixes for various issues including major crash fixes for 
Silverlight/Windows Phone 7Basic .Net serialization support for some core 
classes e.g. INode, IGraph, SparqlResultSetNew asynchronous callback based 
APIs for various features to provide better Silverlight/Windows Phone 7 
support and to make it easier to write async RDF/SPARQL based 
applicationsNew features in the Configuration API and our ASP.Net 
integration to provide detailed control of writer behaviour with regards to 
things like compression, pretty printing, DTD usage etc - see [3] for 
detailsAdded a new ExplainQueryProcessor that can be used to explain the 
evaluation of queries using our Leviathan engineRefactored the 
LeviathanQueryProcessor to make it much easier to extendSupport for some 
experimental advanced algebra optimisations such as parallelised union 
evaluation (disabled by default)Expanded the Handlers API so that you can 
use it to stream process RDF and SPARQL Results from a wider variety of 
data sources including SPARQL endpoints, any IGenericIOManager instance and 
SPARQL Queries in general.This release also marks the introduction of a new 
packaging model where some features are incorporated into separate DLLs 
from the core library.  As of this release as well as the Core library 
(dotNetRDF.dll) - which now comes in 4 different versions: .Net 3.5, .Net 
3.5 Client Profile, Silverlight 4 and Silverlight 4 for Windows Phone 7 - 
you will also find two data providers - Data.Virtuoso and Data.Sql
Data.Virtuoso (dotNetRDF.Data.Virtuoso.dll) contains the OpenLink Virtuoso 
functionality previously found in the core library thus allowing us to 
remove OpenLink.Data.Virtuoso.dll as a dependency from the core library so 
users who don't need this feature have a smaller dependency footprint.
Data.Sql (dotNetRDF.Data.Sql.dll) contains our new SQL backend called the 
ADO store which currently supports Microsoft SQL Server and SQL Azure only. 
 This backend replaces the legacy SQL store from the core library and we'll 
be providing documentation and tooling for migrating from the old format to 
the new format in the next few days so please keep an eye on the mailing 
list.
Note - As another dependency change dotNetRDF now uses 
Newtonsoft.Json.Net35.dll since the main Json.Net build is now targeted at 
.Net 4.0, we plan to move to .Net 4.0 as the primary build next year though 
we will continue to provide a .Net 3.5 build
All of these libraries are now also available via NuGet for those using 
VS2010 and the NuGet plugin.
The latest release of the Toolkit incorporates the following 
changes:Support for our new SQL backend in Store ManagerNamespace 
declarations from queries are now used to format SELECT results in 
StoreManager and SparqlGUIQuery Explanation features in SparqlGUISupport 
for configuring advanced options when using the Save With functionality in 
rdfEditorFaster and more memory efficient syntax validation in rdfEditorNew 
rdfSqlStorage tool for managing our new SQL backendAs always we aim to 
ensure that the library and toolkit continues to stabilise and improve over 
time, if you have any suggestions, feedback, bug reports, patches etc 
please let us know via the mailing lists.
