journal metadata

We’ve added 2 new columns to the journal CSV.

In a series of enhancements to article metadata, we have released the third today.*

If you are familiar with DOAJ metadata then you probably already know that you can download a CSV file which contains the journal-level metadata for all the journals in DOAJ. It is updated every 30 minutes and is probably one of the most popular metadata services we have. It is certainly the best way to get an overview of all the journals in DOAJ.

Today, we’ve released a new version of that file which adds two new columns to it: the number of article records added to a journal in DOAJ and the date that the last article was added. (Columns BF and BG respectively)

The columns were added for two reasons:

  1. To give greater transparency to the information which we display on our homepage whcountere we state that 77% of the journals in DOAJ have article content loaded to them. This is slightly misleading because a journal which uploaded only 5 articles to us in 2013 is counted in that 77%. It is more interesting to know how recent the articles are from a particular title and how much content they have uploaded to us. While this information has always been available by selecting a journal ISSN and using the ‘articles’ filter in Search, we’ve never been able to show all the information in one place.I think that this development will be welcomed by all our users, especially publishers, librarians and those doing research on open access publishing developments.
  2. To allow us to review those journals which have been awarded the DOAJ Seal and remove that Seal from those which are not supplying article metadata to us. Supplying article metadata is one of the 7 Seal criteria and we haven’t yet been able to check, in an efficient manner, which journals are sticking to their promise. [In the application form, we ask if journals “intend” to supply metadata to us.] It’s going to take deeper analysis to get the final figure but I can see very quickly that 25 journals are going to lose their Seal.

I’d love to know what you think about this development so, as usual, do leave a comment or a question, or email me directly: dom@doaj.org.

P.S. The other development which I will post about soon is the removal of duplicated articles from the DOAJ database. More on that when I have it.

*The first and second developments are described in this blog post from February.

Full DOAJ data dump now available

“We’re going to a hackathon and would love to work with DOAJ’s data! Do you have a dump of all DOAJ data?”

“Er, no. Sorry. I mean, we could get it for you but it will take a while. You could probably get it yourself if you know how to extract the JSON… When do you need it for?”

“Tomorrow.”

“Oh.”

We’ve had this conversation a few times. Or had requests from eager individuals and organisations who want to use the rich offerings of the DOAJ metadata. They’ve told us of the wonderful things they could do with the data (slicing, reporting, analysing, apps, databases, software…) and we’ve never been able to help them in good time. But now, we can….

Introducing, full data dumps of ALL the metadata in DOAJ, both journals and articles: https://doaj.org/public-data-dump

So what? Well, let me suggest to you why these are a good thing:

  • For the journal metadata, the CSV is really the only easy-to-use format. The journal data dump provides another way to do this.
  • The data dumps are updated weekly, so can keep you up-to-date on a reasonably short delay. (There is no change feed, just a full dump.)
  • When you want all of the DOAJ data for any reason, you can just take it!
  • Deep paging on the search API is no longer permitted – search is for search, not harvesting. The data dump allows you to harvest.
  • Whenever you want a subset of the DOAJ data, you can just download the data dump, then filter it locally for your needs. For example, if you are a publisher and you want to see all of your metadata in DOAJ, that is all in this data dump, and you can then filter by ISSN
  • You can use it to enhance any local data in your own system or database: you may have basic article metadata in your system, and you want to extend it with DOAJ metadata.
  • If you want to aggregate publications data from multiple sources, this is one way of quickly getting that information from DOAJ (versus using OAI-PMH).
  • These data dumps are more metadata rich than OAI-PMH
  • You may want to use the data for analysis or data mining or other forms of research, or hackathons.
  • The data dumps are also useful as a test dataset.

So there you have it. Despite a rather awkward name, data dumps are A Good Thing.

We’d love to know what you think, so do please leave a comment here or send us feedback: feedback@doaj.org

Are you using an up-to-date version of DOAJ metadata? Apparently not.

Did you know that DOAJ’s metadata refreshes every hour? Given how many changes we, the DOAJ Team, make to the database on a weekly basis plus all the article metadata which is continuously being uploaded to us, the hourly update is absolutely necessary. DOAJ is seeing more use of its API than ever before (2018 total: 266,255,000 hits; 2017 total: 187,212,674) and most of that is by publishers uploading articles.

DOAJ metadata is EVERYWHERE. It is incorporated into all the major discovery services, other online databases and many library catalogues.

You might remember this post of mine from 2017, where I explained that third parties using our data may not have a recent copy of it. We know for a fact that some systems downstream of our data only update the copy every 6 months and, sadly, we get many emails from end users asking why they can’t find an article.

So if you are a researcher, reading this and wondering what happened to that article in DOAJ which is listed in your library catalogue or discovery service, contact your librarians and ask them to update their metadata. If you’re a librarian then do please reach out to sources responsible for your metadata and get them to update their DOAJ metadata.

If you have any questions about this or need some help in getting a more recent copy of our metadata then do leave a comment here or contact us at feedback@doaj.org.

Our new CSV file is online!

Our new, improved CSV file of journal metadata is now online and ready to be downloaded!

The updated file includes all of the new information that we have been collecting and recently started displaying with our site upgrade such as APC information, whether the journal is part of an archiving program, which type of peer review and more! The old file had 17 columns of information; the new one has 54!

Remember that the amount of information in the CSV will increase as each journal has their reapplication accepted to remain indexed in DOAJ. There are currently 510 journals with the new information completed.

All information in the CSV file is shared with you under the terms of a CC BY-SA license.

As always, let me know if you have feedback or questions!
