+This is a bigdata (R) snapshot release.  This release is capable of loading 1B
+triples in under one hour on a 15 node cluster and has been used to load up to
+13B triples on the same cluster.  JDK 1.6 is required.
+
+See [1] for instructions on installing bigdata(R), [2] for the javadoc and [3]
+and [4] for news, questions, and the latest developments.  For more information
+about SYSTAP, LLC and bigdata, see [5].
+
+Please note that we recommend checking out the code from SVN using the tag for
+this release.  The code will build automatically under eclipse.  You can also
+build the code using the ant script.  The cluster installer requires the use of
+the ant script.  You can checkout this release from the following URL:

+New features:
+
+- This release provides a bug fix for issue#118.  Upgrade to this release is
+  advised.  See https://sourceforge.net/apps/trac/bigdata/ticket/118 for details.
+
+- Inlining XSD numerics, xsd:boolean, or custom datatype extensions
+  into the statement indices.  Inlining provides a smaller footprint
+  and faster queries for data using XSD numeric datatypes.  In order
+  to introduce inlining we were forced to make a change in the
+  physical schema for the RDF database which breaks binary
+  compatibility for existing stores.  The recommended migration path
+  is to export the data and import it into a new bigdata instance.
+
+- Refactor of the dynamic sharding mechanism for higher performance.
+
+- The SparseRowStore has been modified to make Unicode primary keys
+  decodable by representing Unicode primary keys using UTF8 rather
+  than Unicode sort keys.  This change also allows the SparseRowStore
+  to work with the JDK collator option which embeds nul bytes into
+  Unicode sort keys.  This change breaks binary compatibility, but
+  there is an option for historical compatibility.
+
+The roadmap for the next releases include:
+
+- Query optimizations;
+
+- Support for high-volume analytic query workloads and SPARQL aggregations;
+
+- High availability for the journal and the cluster;
+
+- Simplified deployment, configuration, and administration for clusters.

+About bigdata: 
+
+Bigdata\xAE is a horizontally-scaled, general purpose storage and computing fabric
+for ordered data (B+Trees), designed to operate on either a single server or a
+cluster of commodity hardware. Bigdata\xAE uses dynamically partitioned key-range
+shards in order to remove any realistic scaling limits - in principle, bigdata\xAE
+may be deployed on 10s, 100s, or even thousands of machines and new capacity may
+be added incrementally without requiring the full reload of all data. The bigdata\xAE
+RDF database supports RDFS and OWL Lite reasoning, high-level query (SPARQL),
+and datum level provenance.
