[Dspace-devel] Metatags for Google Scholar

[David Palmer]

I read the Google Scholar notes on indexing.
http://scholar.google.com/intl/en/scholar/inclusion.html
Which suggests that GS will use meta tags in HTML from DC, Prism, and
another un-named scheme,
ex., "meta name="citation_title" content="The..."

This example from the DSpace demo site,
http://demo.dspace.org/xmlui/handle/1842/171
[view page source]
Uses only one of the meta tag schemes.

But where is the definitive list of tags, and the namespace that GS will
use? Must we use DCTERMS also?

I see various examples of other pages using HTML meta tags

And a blog post from NPG,

tml

Oh, what to do?

Hi David,

So to be clear, the following (taken from the demo.dspace.org link you include below) are the tags we are including for Google Scholar...

<meta content="http://demo.dspace.org/xmlui/handle/1842/171" name="citation_abstract_html_url" />
<meta content="Research Paper" name="citation_keywords" />
<meta content="Einstein; Creel, James Melton; Jingleheimerschmit, John Jacob" name="citation_authors" />
<meta content="A Brugia malayi Homolog of Macrophage Migration Inhibitory  Factor Reveals an Important Link Between Macrophages and  Eosinophil Recruitment During Nematode Infection" name="citation_title" />
<meta content="http://demo.dspace.org/xmlui/handle/1842/171" name="citation_fulltext_html_url" />
<meta content="The American Association of Immunologists" name="citation_publisher" />
<meta content="2010-06-23" name="citation_date" />

The "unnamed" schema (in the citation_ format) is of Google Scholar's own making.  It isn't required that it be name-spaced in any way.

Does this answer your question?

David, have a look at the configuration file:

  http://scm.dspace.org/svn/repo/dspace/trunk/dspace/config/crosswalks/google-metadata.properties

If the fields are not mapped to an DC field, they are not included.

The Google Scholar page,

        http://scholar.google.com/intl/en/scholar/inclusion.html

gives several more tags than are shown in the DSpace demo record.

        http://demo.dspace.org/xmlui/handle/1842/171

such as,

citation_volume

citation_issue

citation_firstpage

citation_lastpage

citation_pdf_url

citational_journal_title

citation_issn

citation_isbn

 

Do we not need this,

Citation_doi

 

Did the recent negotiation, DSpace with Google Scholar people decide that these were not needed?

 

The above was for a journal article.  Is DSpace 1.7 (1.6?) smart enough to change the metadata to include the following for other types?  What drives this change of metadata?  That value in dc.type ?

Citation_conference_title

Citation_dissertation_institution

Citation_technical report_institution

Citation_technical_report_number

Citation_patentnumber

 

In the DSpace example, these DC tags, given on the Google Scholar page, do not show,

dc.citation.spage

dc.citation.epage

dc.citation.volume

dc.citation.issue

dc.citation.relation.ispartof

 

Many thanks

David Palmer
