        Usage
        =====
        
        Export
        ------
        
        Use the form with the URL ``/@@export_content``, and select which content type you want to export:
        
        .. image:: ./docs/export.png
        
        The downloaded json-file will have the name of the selected type, e.g. ``Folder.json``.
        
        The exports for members, relations, localroles and relations are linked to in this form but can also be called individually: ``/@@export_members``, ``/@@export_relations``, ``/@@export_localroles``, ``/@@export_translations``, ``/@@export_ordering``, ``/@@export_discussion``.
        
        
        Import
        ------
        
        Use the form with the URL ``/@@import_content``, and upload a json-file that you want to import:
        
        .. image:: ./docs/import.png
        
        
        The imports for members, relations, localroles and relations are linked to in this form but can also be called individually: ``/@@import_members``, ``/@@import_relations``, ``/@@import_localroles``, ``/@@import_translations``, ``/@@import_ordering``, ``/@@import_discussion``.
        
        As a last step in a migration there is another view ``@@reset_modified_date`` that resets the modified date on imported content to the date initially contained in the imported json-file. This is necessary since varous changes during a migration will likely result in a updated modified-date. During import the original is stored as ``obj.modification_date_migrated`` on each new object and this view sets this date.
        
        
        Use-cases
        =========
        
        Migrations
        ----------
        
        When a in-place-migration is not required you can choose this addon to migrate the most important parts of your site to json and then import it into a new Plone instance of your targeted version:
        
        * Export content from a Plone site (it supports Plone 4 and 5, Archetypes and Dexterity, Python 2 and 3).
        * Import the exported content into a new site (Plone 5.2+, Dexterity, Python 3)
        * Export and import relations, translations, users, groups and local roles.
        
        It does not support any of the following data from your database:
        
        * content revisions
        * registry-settings
        * portlets
        * theme
        * installed addons
        
        Other
        -----
        
        You can use this addon to
        
        * Archive your content as json
        * Export data to prepare a migration to another system
        * Combine content from mutiple plone-sites into one.
        * Import a plone-site as a subsite into another.
        * Import content from other systems as long as it fits the required format.
        * ...
        
        Details
        =======
        
        Export content
        --------------
        
        Exporting content is basically a wrapper for the serializers of plone.restapi:
        
        .. code-block:: python
        
            from plone.restapi.interfaces import ISerializeToJson
            from zope.component import getMultiAdapter
        
            serializer = getMultiAdapter((obj, request), ISerializeToJson)
            data = serializer(include_items=False)
        
        Import content
        --------------
        
        Importing content is a elaborate wrapper for the deserializers of plone.restapi:
        
        .. code-block:: python
        
            from plone.restapi.interfaces import IDeserializeFromJson
            from zope.component import getMultiAdapter
        
            container.invokeFactory(item['@type'], item['id'])
            deserializer = getMultiAdapter((new, self.request), IDeserializeFromJson)
            new = deserializer(validate_all=False, data=item)
        
        
        Use for migrations
        ------------------
        
        A main use-case of this package is migration from one Plone-Version to another.
        
        Exporting Archetypes content and importing that as Dexterity content works fine but due to changes in field-names some settings would get lost. For example the setting to exclude content from the navigation was renamed from ``excludeFromNav`` to ``exclude_from_nav``.
        
        To fix this you can check the checkbox "Modify exported data for migrations". This will modify the data during export:
        
        * Drop unused data (e.g. `next_item` and `components`)
        * Remove all relationfields
        * Change some fieldnames that changed between AT and DX
        
          * ``excludeFromNav`` → ``exclude_from_nav``
          * ``allowDiscussion`` → ``allow_discussion``
          * ``subject`` → ``subjects``
          * ``expirationDate`` → ``expires``
          * ``effectiveDate`` → ``effective``
          * ``creation_date`` → ``created``
          * ``modification_date`` → ``modified``
          * ``startDate`` → ``start``
          * ``endDate`` → ``end``
          * ``openEnd`` → ``open_end``
          * ``wholeDay`` → ``whole_day``
          * ``contactEmail`` → ``contact_email``
          * ``contactName`` → ``contact_name``
          * ``contactPhone`` → ``contact_phone``
        
        * Update view names on Folders and Collection
        * Export ATTopic and their criteria to Collections with querystrings
        * Update Collection-criteria (TODO)
        * Fix image links and scales (TODO)
        
        
        Control creating imported content
        ---------------------------------
        
        Imported content is initially created with ``invokeFactory`` using portal_type and id of the exported item before deserialing the rest of the data.
        You can set additional values by specifying a dict ``factory_kwargs`` that will be passed to the facory.
        Like this you can set values on the imported object that are expected to be there by subscribers to IObjectAddedEvent.
        
        
        Notes on speed and large migrations
        ===================================
        
        Exporting and importing large amounts of content can take a while. Export is pretty fast but import is constrained by some features of Plone, most importantly versioning:
        
        * Importing 5000 Folders takes ~5 minutes
        * Importing 5000 Documents takes >25 minutes because of versioning.
        * Importing 5000 Documents without versioning takes ~7 minutes.
        
        When exporting large numbers of binary files you will get huge json-files and may run out of memory. Options to export the blob-filepath instead are discussed in https://github.com/collective/collective.exportimport/issues/17.
        
        
        Customize export and import
        ===========================
        
        This addon is designed to be adapted to your requirements and has multiple hooks to make that easy.
