Introduction

This API is responsible for uploading files to storage. mod-data-import module use uploaded files for parsing and importing files to storage and another FOLIO modules usage. File Upload API provides an ability to upload several files and store state of uploaded files. A user can delete or add another file from uploading session.

Entities

UploadDefinition

Upload Definition entity describes an upload process and contains a list of file definitions. Each file upload session process starts from creating UploadDefinition.

Field Description
id UUID for an UploadDefinition entity
metaJobExecutionId UUID of JobExecution process for all linked files. Specific for data-import application.
status Show the current state of the upload process. Can be one of: "NEW", "IN_PROGRESS", "LOADED", "COMPLETED"
createDate Date and time when the upload definition was created
fileDefinitions Array of the FileDefinition entities. Each FileDefinition describes particular state of the file
metadata Standard field with metainformation about entity

FileDefinition

File Definition entity describes an upload process of particular file and store this process's state.

Field Description
id UUID for an FileDefinition entity
sourcePath The path to the file location in the storage. Readonly
name Name of the file with its extension. This field is required.
status Show the current state of the upload file. Can be one of: "NEW", "UPLOADING", "UPLOADED", "ERROR"
jobExecutionId UUID of the file's JobExecution process. Specific for data-import application.
uploadDefinitionId UUID of UploadDefinition related to this file
createDate Date and time when the file definition was created
uploadedDate Date and time when the file was uploaded
size Size of the file in Kbyte
uiKey Unique key for the file definition on user interface before entity saved

File Upload API

For all necessary file upload lifecycle operations mod-data-import provides following endpoints:

Method URL ContentType Description
POST /data-import/uploadDefinitions application/json Create new UploadDefinition
GET /data-import/uploadDefinitions Get list of UploadDefinitions by query
GET /data-import/uploadDefinitions/{uploadDefinitionId} Get single definition by UUID
PUT /data-import/uploadDefinitions/{uploadDefinitionId} application/json Update definition by UUID
DELETE /data-import/uploadDefinitions/{uploadDefinitionId} Delete UploadDefinition by UUID
POST /data-import/uploadDefinitions/{uploadDefinitionId}/files application/json Add new FileDefinition to UploadDefinition
DELETE /data-import/uploadDefinitions/{uploadDefinitionId}/files/{fileId} Delete FileDefinition from UploadDefinition by UUID
POST /data-import/uploadDefinitions/{uploadDefinitionId}/files/{fileId} application/octet-stream Upload file data to backend storage

File Upload Workflow

Create UploadDefinition

Each file uploading process starts from creating new UploadDefinition. Send POST request with list of file names for creating new UploadDefinition.
