Is there a known API or any method to fetch the "author listed keywords" for all publications in DOAJ.org or PMC open access subset ?
I tried the ftp of PMC open access subset but the XML files only have IDs, abstract, title, author and affiliations as the metadata to any article. I am looking to mass fetch the keywords too listed with each publication.
Also, I saw few threads around the same but still haven't found the answer I was looking for. So have made a new post.
Any help is much much appreciated.
Thanks,
Asmi
Both platforms have OAI-PMH interfaces:
http://doaj.org/oai.article?verb=Identify
http://www.pubmedcentral.nih.gov/oai/oai.cgi?verb=Identify
DOAJ seems to provide keywords in the dc:subject
field of its output in the oai_dc
format. PubMedCentral provides them in their pmc
format, in their <kwd-group/>
tag.
Just use an OAI-PMH client library in your favourite programming language. You can find some here: https://www.openarchives.org/pmh/tools/tools.php
