For EMBL-EBI pages there are few loose groups of metatags that are recommended for your pages.
These control the look of the local masthead area.
You could achieve a similar look through CSS, but this method offers more reusability and smoother updates in future changes and improvements.
<meta name="ebi:head-color" content="#091314">
<meta name="ebi:head-image" content="//ebiwd.github.io/EBI-Framework/images/backgrounds/embl-ebi-background-4.jpg">
Recommended image size: 2462px wide, 322px high
These metatags help ensure content the Web Content Committee can understand who owns content, and if content is still current.
(note: future improvements regarding granularity are expected druing 2018)
<meta name="ebi:owner" content="John Doe"> <!-- Who should be contacted about changes -->
<meta name="ebi:review-cycle" content="30"> <!-- In days, how often should the content be reviewed -->
<meta name="ebi:last-review" content="2015-12-20"> <!-- The last time the content was reviewed -->
<meta name="ebi:expiry" content="2016-01-20"> <!-- When this content is no longer relevant -->
