There are two components for input/output: Exporters: Process (composite) HoloViews objects one at a time. For instance, an exporter may render a HoloViews object as a svg or perhaps pickle it. Archives: A collection of HoloViews objects that are first collected then processed together. For instance, collecting HoloViews objects for a report then generating a PDF or collecting HoloViews objects to dump to HDF5.

References are used by Collector to capture the state of an object at collection time. One particularly important property of references is that they should be pickleable. This means that you can pickle Collectors so that you can unpickle them in different environments and still collect from the required object. A Reference only needs to have a resolved_type property and a resolve method. The constructor will take some specification of where to find the target object (may be the object itself). ct)z Returns the type of the object resolved by this references. If multiple types are possible, the return is a tuple of types. NotImplementedErrorselfs r resolved_typezReference.resolved_typeBs "!rNct)z Return the referenced object.

This mechanism is designed to be very general so here are a few examples: Pickling: Native Python, supported by HoloViews. Rendering: Any plotting backend may be used (default uses matplotlib) Storage: Saving to a database (e.g. SQL), HDF5 etc. )z image/svg+xmlz text/htmlz text/jsonaz Function that generates the metadata key from the HoloViews object being saved.

Ability to save and load components of a Layout independently. 3. Support for metadata per saved component.
