Dublin Core Element Metatags

Useful? Useless? Beneficial? Harmful?

[pmkpmk]

My CMS (Typo3) automatically inserts regular Metatags and the so called "Dublin Core Elements".

Regular tags inserted by the CMS:

<META NAME="Description" CONTENT="">
<META NAME="Keywords" CONTENT="">
<META NAME="Robots" CONTENT="">
<META NAME="Copyright" CONTENT="">
<META NAME="Author" CONTENT="">
<META NAME="Distribution" CONTENT="">
<META NAME="Rating" CONTENT="">

Dublin Core tags:

<META NAME="DC.Description" CONTENT="">
<META NAME="DC.Subject" CONTENT="">
<META NAME="DC.Rights" CONTENT="">
<META NAME="DC.Language" scheme="NISOZ39.50" CONTENT="">
<META NAME="DC.Creator" CONTENT="">
<LINK REL="schema.dc" HREF="http://purl.org/metadata/dublin_core_elements">

If I fill out the corresponding variables, both sets of tags get filled in. No I wonder if I need them both? Or only one? Does it hurt to have the Dublin-Elements? Can I get rid of the "classical" ones if I have the DC-stuff in there? Should I get rid of the DC-Elements?

Any advice would be appreciated.

There all pretty much useless except for the description and possibly the keywords tag. The dublin core is not used at all, and the rest of the classics are a waste of space.

They are totally useless. Waste of space. Also puts away your main content further away from the begining of the page, this giving it less weight in SEs.

Thanks, that's what I wanted to hear. They're already out...

Maybe Keep your Robots tag. If bots are eating to much of your bandwidth you could add a revisit tag?

As far as I know, the revisit-after tag is total bulls**t. There was only one search engine who ever used it, and that one had a geographical limit on Canada (if I recall it right).

In purely SEO terms, the Dublin Core meta tags are useless, yes - but they can be useful in terms of searching your own site or documents, for example on an intranet which uses your own search engine. As others have said, on most public sites they are a waste of bandwidth.

Thanks for the link your right! I didnt know that just like pageoneresults says:

I just seen it everywhere i looked...

Sorry for that bit of bad advice then ;)
