The term "legacy" in Statistics

[George Kozak]

Hi,

We are using DSpace 6.3 (XMLUI).  An author pointed out to us that the "View Usage Statistics" (https://ecommons.cornell.edu/handle/1813/7642/statistics) for his book in our DSpace has 2 categories:

A ... 3549
A ...(legacy) 755

He asked what "legacy" means.  I wasn't sure, does someone know?

Thanks!

Hi George,

the (legacy) note is added here:

https://github.com/DSpace/DSpace/blob/820722d2e6e848a5b486c56b6596ce1473d16792/dspace-api/src/main/java/org/dspace/statistics/content/StatisticsDataVisits.java#L543

By skimming through the code, I think it means that these are usage events that are still present in SOLR, while the original bitstream has been deleted.

This seems to check out when looking at:

https://ecommons.cornell.edu/handle/1813/7642

The two public bitstreams have sequence IDs 4 and 6, meaning that you likely had additional bitstreams there, sequence id 1, 2, 3 and 5, and that those might be deleted?

hope this helps,

Bram

Hi George,

Emilio Lorenzo from Arvo.es sent me an off-list reply that I may have got it wrong here.

It's likely that legacy refers to the legacy item-id system, with sequential ids (DSpace 5 and earlier), as opposed to the new uuid approach since DSpace 6.

This is discussed and documented here: https://jira.lyrasis.org/browse/DS-3602

I didn't look closely enough and was wrong in my initial reply. Thanks again Emilio for the correction !!!

cheers,

Bram

Thanks, again, Bram.

So, am I right in assuming that “legacy” can be applied to both deleted bitstreams and items affected by the switch to uuids in DSpace 6?

We migrated from DSpace 5 to DSpace 6, and have the same display. We started the task of migrating the DSpace 5 and earlier stats to DSpace 6 ones, as outlined in DS-3602, so they would all be in one category, but have not finished. I would add them together to determine the total downloads.

Hi George,

I think stats are only shown for bitstreams that haven't been deleted.

As a test, I deleted a bitstream from an item in demo.dspace.org, that previously had download stats, and those are now totally gone from:

http://demo.dspace.org/xmlui/handle/10673/81/statistics

best regards,

Bram

Is DS-4066 not related?

https://jira.lyrasis.org/browse/DS-4066

This patch will be introduced with the 6.4 rollout despite much earlier target dates.

https://wiki.lyrasis.org/display/DSPACE/DSpace+6.4+Release+Status

There will be a new command for migrating pre-6.x statistics:
