- // ## VIE constructor
- //
- // The VIE constructor is the way to initialize VIE for your
- // application. The instance of VIE handles all management of
- // semantic interaction, including keeping track of entities,
- // changes to them, the possible RDFa views on the page where
- // the entities are displayed, and connections to external
- // services like Stanbol and DBPedia.
- //
- // To get a VIE instance, simply run:
- //
- // var vie = new VIE();
- //
- // You can also pass configurations to the VIE instance through
- // the constructor. For example, to set a different default
- // namespace to be used for names that don't have a namespace
- // specified, do:
- //
- // var vie = new VIE({
- // baseNamespace: 'http://example.net'
- // });
- //
- // ### Differences with VIE 1.x
- //
- // VIE 1.x used singletons for managing entities and views loaded
- // from a page. This has been changed with VIE 2.x, and now all
- // data managed by VIE is tied to the instance of VIE being used.
- //
- // This means that VIE needs to be instantiated before using. So,
- // when previously you could get entities from page with:
- //
- // VIE.RDFaEntities.getInstances();
- //
- // Now you need to instantiate VIE first. This example uses the
- // Classic API compatibility layer instead of the `load` method:
- //
- // var vie = new VIE();
- // vie.RDFaEntities.getInstances();
- //
- // Currently the Classic API is enabled by default, but it is
- // recommended to ensure it is enabled before using it. So:
- //
- // var vie = new VIE({classic: true});
- // vie.RDFaEntities.getInstances();

- // ### Namespaces in VIE
- // VIE supports different ontologies and an easy use of them.
- // Namespace prefixes reduce the amount of code you have to
- // write. In VIE, it does not matter if you access an entitie's
- // property with
- // `entity.get('<http://dbpedia.org/property/capitalOf>')` or
- // `entity.get('dbprop:capitalOf')` or even
- // `entity.get('capitalOf')` once the corresponding namespace
- // is registered as *baseNamespace*.
- // By default `"http://viejs.org/ns/"`is set as base namespace.

- // registered namespaces, refer to the

- // tend to make their usage pretty circuitous. The ``VIE.Namespaces(...)`` class provides VIE
- // with methods to maintain abbreviations (akak **prefixes**) for namespaces in order to
- // alleviate their usage. By default, every VIE instance is equipped with a main instance
- // of the namespaces in ``myVIE.namespaces``. Furthermore, VIE uses a **base namespace**,
- // which is used if no prefix is given (has an empty prefix).
- // In the upcoming sections, we will explain the
- // methods to add, access and remove prefixes.
- // ## VIE.Namespaces(base, namespaces)
- // This is the constructor of a VIE.Namespaces. The constructor initially
- // needs a *base namespace* and can optionally be initialised with an
- // associative array of prefixes and namespaces. The base namespace is used in a way
- // that every non-prefixed, non-expanded attribute or type is assumed to be of that
- // namespace. This helps, e.g., in an environment where only one namespace is given.
- // **Parameters**:
- // *{string}* **base** The base namespace.
- // *{object}* **namespaces** Initial namespaces to bootstrap the namespaces. (optional)
- // **Throws**:
- // *{Error}* if the base namespace is missing.
- // **Returns**:
- // *{VIE.Attribute}* : A **new** VIE.Attribute object.
