POINTS OF EMPHASIS
Achieving greater conceptual and semantic consistency in the use of EAD.
Exploring mechanisms whereby EAD-encoded information might more seamlessly and effectively connect with, exchange, or incorporate data maintained according to other protocols.
![Page 8: EAD Revision Progress Report, 2012-08-08](https://reader035.vdocuments.us/reader035/viewer/2022062614/546b78d6af795996668b4d9e/html5/thumbnails/8.jpg)
POINTS OF EMPHASIS
Improving the functionality of EAD for representing descriptive information created in international and particularly in multilingual environments.
Being mindful that a new version will affect current users.

REDUCE SEMANTIC OVERLOAD
<note> 8 distinct uses in EAD:
<notestmt> <titlepage> or <div> [in <frontmatter> <did> <did> sibling Within <did> siblings [as a block element] Recursively within <note> Within block elements like <p> [as mixed
content] <namegrp>

UPDATE ACCESS TERMS
Split mixed content and block uses of access term elements into separate elements Separate semantics of the following:
<p>Includes correspondence from <persname>John Lennon.</persname></p>
<controlaccess><persname>Lennon, John.</persname>
</controlaccess>

ALIGN WITH XHTML
Minor tweaks to <table> Minor tweaks to <list> Remove <table>, <list>, and
<chronlist> from within <p> Limit <blockquote> to a block element,
add <quote> for inline use.

SIMPLIFY LINKS
Consolidate <extref>, <extptr>, <ref>, and <ptr> to just <ref>
Remove linking attributes from assorted elements, e.g. <title>
Deprecate extended links <daogrp> <linkgrp>
Remove XLINK namespace, but implement linking attributes isomorphic with XLINK

REDUCE MIXED CONTENT
Reduce mixed content by more carefully considering what elements are appropriate within a given element
Examples: Limit available children of <container> to
<emph> and <ref> Limit available children of <langmaterial>
to <languagef>, <emph>, and <ref>
