Entity API

Overview

Use the Entity API in order to manage IBS-Entities of different types.

Create

Parameter	Type	Comment
action	String	create see also API - General parameters
datasource	String	the url of the file to fetch
type	String or int
hrid	String
description	String
expirydate	timestamp	if set, the entity will be deleted after the expirydate
mimetype	String	only for type = 1 (File) If not given, then the mime-type is extracted from the ending of the datasource
customdata	JSON	possible entries: de.jenomics.ikona.binarystore.worker.schedule.StandardScheduleProcessor.fetchcount: int value = number of downloads. The first one is downloaded and the other ones are copied from the download de.jenomics.ikona.binarystore.worker.schedule.StandardScheduleProcessor.fetchduedate: timestamp, sets the time when a download can start de.jenomics.ikona.binarystore.worker.schedule.StandardScheduleProcessor.copyduedate: timestamp, sets the time when a download should be copied - only if downloads > 1 de.jenomics.ikona.binarystore.worker.schedule.StandardScheduleProcessor.fetchstorage: uuid of the storage that should be used for download de.jenomics.ikona.binarystore.worker.schedule.StandardScheduleProcessor.copystorage: uuid of the storage that should be used for copying - only if downloads > 1 filesize: if given, the filesize is compared to this value after fetching checksum: the crc-checksum in hex-format. If given, the crc-checksum of the file after download is compared to this one
pin	boolean	set this to true in order to pin the entity, i.e. create a self-referencing relation set this to false in order to unpin the entity, i.e. delete the self-referencing relation see Reference API
parent	uuid	uuid of the parent entity - if addreferences is also given, parent is ignored, see also Reference API
child	uuid	uuid of the child entity - if addreferences is also given, child is ignored, see also Reference API
addreferences	JSON	JSON with "children" = a list of child-uuids and / or "parents" = an array of parent-uuids to be added, e.g. {"children" : ["428A57C1-B006-44AE-AAF3-7C72B3A28FE0" , "C879A548-7827-4628-ADF3-AE8A01C314F5"], "parents" : ["41C3CB6B-BC23-40BF-8582-790BDB904CA5", "0FF44487-C6D6-4960-A4D3-E67B73D897CF" ]}, see also Reference API
removereferences	JSON	JSON with "children" = a list of child-uuids and "parents" = an array of parent-uuids to be removed, see also Reference API
refid	String	the id of an external system
filesize	long	the size in bytes of the file, given at datasource. If given, this value is used to check, whether the fetch succeeded correctly. FYI: The entity represents the logical file. Internally the fetched file is represented as a StorageEntity. The filesize of a StorageEntity may differ from the logical one, as we could implement a compression or encryption depending on the storage that is used. Therefore the values of this filesize and the one of the according StorageEntity may be different!
checksum	String	the crc-checksum of the file, give at datasource. If given, this value is used to check, whether the fetch succeeded correctly. FYI: The entity represents the logical file. Internally the fetched file is represented as a StorageEntity. The checksum of a StorageEntity may differ from the logical one, as we could implement a compression or encryption depending on the storage that is used. Therefore the values of this checksum and the one of the according StorageEntity may be different!

addreferences	JSON	JSON with "children" = a list of child-uuids and / or "parents" = an array of parent-uuids to be added, e.g. {"children" : ["428A57C1-B006-44AE-AAF3-7C72B3A28FE0" , "C879A548-7827-4628-ADF3-AE8A01C314F5"], "parents" : ["41C3CB6B-BC23-40BF-8582-790BDB904CA5", "0FF44487-C6D6-4960-A4D3-E67B73D897CF" ]}, see also Reference API

Internally the fetched file is represented as a StorageEntity. The filesize of a StorageEntity may differ from the logical one, as we could implement a compression or encryption depending on the storage that is used. Therefore the values of this filesize and the one of the according StorageEntity may be different!
