    October 07, 2016

    🚀 Current release marks community build number two, introducing major change to data layout and bringing new features to Gremlin.

    Storage format changed slightly. We highly recommend to do a clean import of the database with a new binary.

    Cayley now honors types of nquad values. IRIs (<name>) were converted to untyped strings (name), so it was possible for nodes with different types to be loaded as a single node. Now Cayley preserves type information, making these nodes separate. Queries that used IRIs without <> quotes will break because of this change. Gremlin now requires IRI it to be in "<follows>" form and the path lib expect these values to be of quad.IRI Go type. The same stands for Strings (aka RDF literals) and BNodes (aka blank nodes, _:name).

    Data loader now recognizes few basic typed literals like "10"^^<http://schema.org/Integer> and converts them into corresponding native type (Int for this example). It may also affect existing queries. Gremlin will automatically convert basic types into corresponding RDF typed literals.

    Highlights:

    • 👍 Typed values support for all backends. Includes types: String, IRI, BNode, Int, Float, Bool, Time.
    • 🆕 New traversals in path lib and Gremlin: HasReverse, Skip, Limit, Count, Unique, Comparison/Filter, Regex.
    • ✅ More consistent backends behavior thanks to unified tests.
    • ⚡️ Updated docs and added examples.
    • ⚡️ Updated Docker image, and added example for it.
    • 🛠 Many, many bugfixes and some optimizations.
