  • v0.6.0 Changes

    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.

  • v0.5.0 Changes

    July 03, 2016

    🏗 We've spun out of the google namespace, so this is community build number one. There's some good chatter in IRC and places, and expect some notes in the mailing list soon. The project isn't dead, it was just resting.

    🚀 Now that we can add contributors, it's time to tag and build a release as a baseline. There may be some turbulence as some longstanding changes get merged over the next version or two, so before we do that, here are some binaries for people to try out the latest.
