DLite is a lightweight cross-platform C library, for working with and
sharing scientific data in an interoperable way.

All data in DLite is represented by an Instance, which is build on a
simple data model.  An Instance is identified by a unique UUID and
have a set of named dimensions and properties.  It is described by its
Metadata.  In the Metadata, each dimension is given a name and
description (optional) and each property is given a name, type, shape
(optional), unit (optional) and description (optional).  The shape of
a property refers to the named dimensions.

When an Instance is instantiated, you must suply a value to the named
dimensions.  The shape of the properties will be set according to
that.  This ensures that the shape of the properties are internally
consistent.

A Metadata is also an Instance, and hence described by its
meta-metadata.  By default, DLite defines four levels of metadata;
instance, metadata, metadata schema and basic metadata schema. The
basic metadata schema describes itself, so no further meta levels are
needed.  The idea is if two different systems describes their data
model in terms of the basic metadata schema, they can easily be made
semantically interoperable.

An alternative and more flexible way to enable interoperability is to
use a common ontology.  DLite provides a specialised Instance called
Collection.  A collection is essentially a container holding a set of
Instances and relations between them.  But it can also relate an
Instance or even a dimension or property of an instance to a concept
in an ontology.  DLite allows to transparently map an Instance whos
Metadata corresponding to a concept in one ontology to an Instance
whos Metadata corresponding to a concept in another ontology.  Such
mappings can easily be registered (in C or Python) and reused,
providing a very powerful system for achieving interoperability.

DLite provides also a common and extendable API for loading/storing
Instances from/to different storages.  New storage plugins can be
written in C or Python.

DLite is released under the MIT license.
