Implement a tool for migrating raw bioassays to derived bioassays

[Nicklas Nordborg]

Future development of BASE may remove things that are not used much anymore. For example, raw bioassays with raw data imported into the database, experiments, array lims, etc.

We have a lot of data at the raw bioassay level but they are also a bit problematic since it is a dead end in the sense that it is not possible to create more child items for other analysis. Until now it has been solved by adding more files and/or annotations to an existing raw bioassay.

It would be a lot more flexible if we could move existing raw bioassays to the derived bioassay level instead. In theory it could be done with batch importers, but in practice it would be better to implement a tool for that.

The general idea is to create a derived bioassay copy of each raw bioassay. The platform/variant/rawdatatype are used to map to a subtype. Existing annotations, files, any-to-any links, etc. are re-linked to the new derived bioassays (they will no longer be available on the raw bioassay).

Below is more detailed description (not yet complete):

Database columns

id	id	A new ID is generated
version	version	Copy
diskusage_id	-	Not used
annotationset_id	annotationset_id	Copy and clear

Annotations

Annotations can be moved to the new derived bioassay by updating the AnnotationSets table with the new id.

AnnotationSets	Comment
id	Keep
version	+1
item_type	Change 264 (=RAWBIOASSAY) to 268 (=DERIVEDBIOASSAY)
item_id	Change to new id

NOTE! Cached annotations (in the static.cache/snapshots-v5 directory) must be deleted. ~The simplest thing is to delete the entire directory and everything in it.~ It is easy to delete from the code since we already have SnapshotManager.removeSnapshots() method.

NOTE! Annotation types that are enabled for raw bioassays but not derived bioassays need to be updated. We can implement this in the tool as well. We would need to insert an entry into the AnnotationTypeItems table for each annotation type:

AnnotationTypeItems	Comment
annotationtype_id	Id of annotation type
item_type	268

Files

Files can be moved to the new derived bioassay by updating the FileSets table with the new id.

FileSets	Comment
id	Keep
version	+1
item_type	Change 264 (=RAWBIOASSAY) to 268 (=DERIVEDBIOASSAY)

Any-to-any links

Links are moved to the new derived bioassay by updating the AnyToAny table. We need to check both the source and target of the links.

AnyToAny	Comment
id	Keep
version	+1
name	Keep
description	Keep
from_id	Keep or change to new id
from_type	Change 264 (=RAWBIOASSAY) to 268 (=DERIVEDBIOASSAY)
to_id	Keep or change to new id
to_type	Change 264 (=RAWBIOASSAY) to 268 (=DERIVEDBIOASSAY)
uses_to	Keep

Change history

The change history is moved to the new derived bioassay by updating the ChangeHistoryDetails table. This will leave the old raw bioassay without a change history. I think we should insert a new entry representing the migration. We should also insert a new entry for the derived bioassay.

ChangeHistoryDetails	Comment
id	Keep
version	+1
history_id	Keep
change_type	Keep
item_id	Change to new id
item_type	Change 264 (=RAWBIOASSAY) to 268 (=DERIVEDBIOASSAY)
change_info	Keep
old_value	Keep
new_value	Keep

A new entry in the ChangeHistory table is created that represents the migration:

ChangeHistory	Comment
id	Generated
version	0
time	Current timestamp
user_id	Id of root user
session_id	Id of current session
client_id	Id of a new client (net.sf.basedb.clients.rba2dba-migration)
project_id	Null
plugin_id	Null
job_id	Null
name	Migrate raw bioassays to derived bioassays

New entries for the raw bioassay and the new derived bioassay in the ChangeHistoryDetails table:

ChangeHistoryDetails	Comment
id	Generated
version	0
history_id	Id of current history
change_type	2 (=UPDATE)
item_id	Id of raw bioassay or derived bioassay
item_type	264 (=RAWBIOASSAY) or 268 (=DERIVEDBIOASSAY)
change_info	Migrated <name-of-rba> from raw bioassay to derived bioassay
old_value	Null
new_value	Null

Added an entry point to the OneTimeFix implementation. The migration can be started with onetimefix.sh migrate_rba2dba -u <root> -p <password> -c <config>

Started to implement the migration utility. It currently count all raw bioassays and load the information about them that is needed. Nothing is yet created or moved.

Move any-to-any links to the new derived bioassays. Needed an extra index on the 'from_type' and 'from_id' columns to make the update quer perform well.

Move the change history to the new derived bioassay. There was an extra complication with the two log entries that are added as part of the migration since we do not want to move them to the derived bioassay. Solved by focring a flush() before the log entries are added.
