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.
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.

@otherlegalstatus Deprecation as a blanket rule for new
removals

HELTER SKELTER
DISENTANGLE DESCRIPTIVE ELEMENTS
Remove <arrangement> from <scopecontent>
Remove <acqinfo> from <custodhist> Remove <legalstatus> from
<accessrestrict> [and promote it to a sibling] Remove <unitdate> from <unittitle> Eliminate recursion
bioghist/bioghist controlaccess/controlaccess Provide alternative using <div>
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>
UPDATE ACCESS TERMS
Enable <part> <controlaccess>
<persname><part>Lennon, John, </part><part>1940-1980</part>
</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
SUPPORT MULTIPLE LANGUAGES
Add language code and script code attributes to each non-empty element
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>
COME TOGETHER
RECONCILIATION WITH EAC-CPF
Replace <eadheader> with <control> Keeping <filedesc> but replacing the rest
Add <relations> at all levels * Improve data model for dates * Improve <chronlist> *
* Pending discussion

LET IT BE
REJECTED PROPOSALS
Eliminate <did> Eliminate <head> Eliminate <abstract> Eliminate numbered components Make <archdesc> a wrapper tag for
components alone Make @level required for all components
