Mass imports/uploads

Overview

This API makes it possible to carry out mass file uploads.
The process is based on jobs and import items attached to these jobs.
An element to be imported consists of a binary and qualification data: the item is a temporary object, which does not exist in the database, but whose simulated view can be obtained at any time.
A job is attached to a user. The process consists in attaching items to be imported to this job, qualifying them, then launching the actual creation of the final objects.
Item qualifications and object creations are asynchronous (asynchronous job works).

An item corresponds to any type of asset. A qualifying property of the same name in two different asset types must absolutely be of the same type (and nature if applicable).

End points

standard URI

All standard endpoints for massimport starts with /api/rest/massimport.

standard generic URI

End points that start with /api/rest/massimport/data have the same characteristics as standard end points of the type /api/rest/{dam/}data.

catalog

GET /api/rest/massimport or GET /api/rest/massimport/data (or GET /api/rest/massimport/catalog)

To get headers, use parameter headers:

GET /api/rest/massimport?headers=true

Jobs end points

Get headers

GET /api/rest/massimport/job/headers

Get job data

GET /api/rest/massimport/job/{jobid}

Parameters:

• withItems, boolean (false by default)
  export also job items data

• withSimu, boolean (false by default)
  export simulation for each item

• resetSimu, boolean (false by default)
  if withSimu=true, force reset of the simulation cache

• maxItems, int (negative means infinite), limit the number of items (default is infinite)

Get job list

GET /api/rest/massimport/job for infinite list

GET /api/rest/massimport/job/list for paginated list

Parameters:

Any standard parameters of list or search query, plus specific parameters (see Get job data)

Show workflow of job

GET /api/rest/massimport/job/workflow

Show new possible workflow action

GET /api/rest/massimport/job/{jobid}/workflow

Create a new job

POST /api/rest/massimport/job

The jobowner is automatically set to surfer that invoke the end point.

Create a new job with data (multipart/form-data)

Provide a json in a field named json (or in a field with your wanted name, and a parameter named jsonproperty to set this name, in form or in query).

By example, set the job name and the job owner (id=11):

Create a new job and attach items

You can attach items to the new job with field named itemIds:

• an array of id of existing items (string or int), or asset uid or uuid (in this case, item will be created)

• a query to select items as as JSonQuery (see Request Language )
  
  

To specify queries to select assets, user the prefix itemIds_ followed by the name of the asset resource (example: itemIds_asset={“owner”:”123”}

Example, with list of items (here ids 1 and 2):

Example with query (here, all items created on june, the 3^rd, 2020):

Example with independent field:

Parameters can be set in query:

• add_itemIds (or itemIds): to add items by id (multiple values)

• add_itemIds_query to add items by query (single value)

• remove_itemIds: to remove items by id (multiple values)

• remove_itemsIds_query to remove items by query

• add_itemIds_ followed by resource name to add assets by id (creating item for asset)

• remove_itemIds_ followed by resource name to remove assets items by id

• add_itemIds_query_ followed by resource name to add asset by query

• remove_itemIds_query_ followed by resource name to remove asset items by query

Delete job

DELETE /api/rest/massimport/job/{id}

parameters:

• withItems (boolean, default is false): if true, reports attached items

• deleteItems (boolean, or string, default is false): if true, remove items, if false, detach item (set job to null). If value is an id of a job, attach items to the job.

• withSecondary (boolean, default is true), delete also secondary jobs

Items end points

Headers

GET /api/rest/massimport/item/headers

Create a new item (binary in body)

Use POST /api/rest/massimport/item, with binary file in body

The filename (this name is the store final filename and will be use to determinate mimetype if the file) must be provided

• either by content-disposition header
  Example: content-disposition: atachment; filaname=”filename.jpg”

• or query parameter
  Example: filename=filename.jpg

The content-type must be provided by content-type header, and can be anything but application/json. Do not use application/json, because this content-type is reserved for metadata : to upload a binary json file, use any other content type (i.e. application/octet-stream). The final mimetype of the file will be determinated from the filename extension.

Example (curl):

Create a new item (multipart/form-data)

Use POST /api/rest/massimport/item, with content-type multipart-formdata

The binary file must be provided in the field named binary. A filename, other than the field content-disposition, can be provided with the query parameter named prop_binary or multipart/form-data field binary : this filename will be the final filename.

Example (curl, with filename in multipart/form-data):

In this mode you can specify data for the item in a json. See the

Example setting target job and name (curl):

Create a new item from an asset

Made as if to create an item from scratch, and on top of that, use asset parameter (or $asset) to specify the source asset as:

• uid: type then id, separated with underscore (example: asset_42)

• uuid

The parameter can be included in the json.

Example (curl), with json in body, targetting job 2:

Add or remove items (asynchronous)

The parameter itemIds used in a job modification request allows to add items to the job or remove items from the job (detach them make them without any job). This parameter can be used as separated parameters (in multipart/form-data field, in query parameter…) or inside the json data description sent to modify properties of the job.

the json contains one or both of the following properties:

• add

  • an array of item ids (string or number)

  • a jsonquery to select items

• remove

  • an array of item ids (string or number)

  • a jsonquery to select items
    
    

Example to add items:

Example to add all items created on june, the 3^rd 2020:

When creating a job, as you can only add items, you can simplify the json by indicating only the value of the add property.

Example to create a job with name “test” with all data in the json description:

Same example with simplified syntax:

Same example with itemIds in its own field:

You can also use query parameters, one to add with name add_itemIds, one to remove with the name remove_itemIds, for ids

Example:

You can also use query parameters, one to add with name add_itemIds_query, one to remove with the name remove_itemIds_query, for query

Example:

The ways are combinable, but if there is a parameter in the multipart/form-data, its query equivalent is ignored.

The request invocation ends immediately and the modifications are scheduled to be done asynchronously. Until the demands are not finished, the job is marked outstanding (you can get this state in the status section of a job data).

Add or remove items (asynchronous)

Do a request on an item to modify the property job (or set it when creating the item).

Example:

Qualify items (asynchronous)

You can schedule items qualification on a job, with the parameter metadata. This parameter works like itemIds parameter (you can put in json, in a multipart/form-data field, in a query parameter).

The value is a json with :

• a property ids, to list the item ids you want to qualify (an array of ids, or a single id, if there is only one items to change)

• tagging data, one or both following properties:

  • type ( or datatype) to set the target type (if different of defaultcollection of the job). If not set, and there is a $resource in data property value, this one is used

  • data: a json, with the same syntax as any API modification

  • workflow : a workflow action name or id

Example:

Example:

Qualify item (synchronous)

To qualify an item, modify it with the parameter metadata, the same as when qualifying items asynchronously (by job), but without ids.

The syntax is the same as standard modification. If you use a json, if a property metadata exists in the resource item, use $metadata.

Extensions (business services)

The class com.noheto.restapi.MassImport from jar restapibs.jar (copy it from plug-in WXM-RESTAPI) provides an API you can use in you own plug-in, to retrieve information about the items to be imported.

Get item target type in your extensions

String MassImport.getDataType(String/id|IObjectReadonly)

Get simulation data in your extensions

com.google.gson.JsonObject MassImport.getItemSimu({wsnoheto.engine.CTSurfer,}{org.apache.log4j.Logger,}String/id|IObjectReadonly,boolean/resetCache)

org.json.JSONObject MassImport.getItemSimuJson({wsnoheto.engine.CTSurfer,}{org.apache.log4j.Logger,}String/id|IObjectReadonly,boolean/resetCache)

Structures

Bases

• massimportjob
  you must use this object and it must have the following fields:

• massimportitem
  item structure. You can use you own object, but you it must have the following fields, in addition to the standard fields:

Workflows

• wkfmassimportjob / wkfmassimportjobaction
  This workflow must not be modified
  
  

• wkfmassimportitem / wkfmassimportitemaction

Fulltext indexation of simulation data

To allow fulltext search within items, item structure must have i18n datachanges field, as well as the associated fields for each desired locale, and these fields must be indexed.

Check the structures

You can check if structures or workflows are valid in the plug-in status page.
