The delivery of SGML encoded documents is most definitely a problem, though
the future looks more promising now than it did a year ago. Changing the
outlook is the development of XML or Extensible Markup Language, an IETF
effort. XML is a subset of the SGML standard, a subset that eliminates some
features that make it difficult to write SGML-aware applications.

The XML development is promising because Sun, MicroSoft, SoftQuad,
Inso/EBT, Netscape (after at first balking) and other developers are
supporting the effort. MicroSoft already has submitted at least two XML
compliant DTDs for discussion to the IETF. If the current trend continues,
and it appears it will, MicroSoft's Internet Explorer and Netscape's
Navigator will support XML display and other applications not possible
using HTML (more profound linking, searching, and metadata (descriptive and
control) for example). There are also likely to be many JAVA applets that
process XML.

The EAD DTD, thanks to good advice from Steve DeRose (Inso) and Debbie
Lapeyre (Mulberry) is nearly compliant with XML specifications, and making
it so is highly unlikely to invalidate current EAD documents. And so it
appears relief is on its way for the SGML browser blues.

In the meantime, though, the following options are available for making
EAD-encoded finding aids available on the Internet:

1) Inso's DynaText/DynaWeb configuration. This requires an outright
purchase of the DynaText/DynaWeb software, or applying for an educational
grant for the same. The grant process takes a bit of time, and the
DynaText/DynaWeb software requires that you have highly skilled technical
support in or available to your repository.

2) SoftQuad's Panorama is available as a "helper" application to the
Windows versions of Netscape and Explorer. Since Panorama does not come
bundled with either browser, the user must download, install, and configure
the software to look at finding aids being pitched to Panorama. Usually
this is a fairly simple process, but occastionally is difficult. Another
weakness is that Panorama's table handling functions are not sufficiently
flexible to handle the <tspecs> in EAD.

3) Translate the SGML into HTML on-the-fly or in advance using various
scripts. This requires that you have staff available that can work with
perl and/or CGI scripts, or you create the finding aids in a database
package that has good exporting support, or you encode your finding aids
using the EAD in exactly the same way as someone else who has developed the
perl/CGI scripts, and "borrow" them. Both UVa and UCSD are participating
with UC Berkeley in projects that involve using the same encoding, and both
institutions are "piping" the SGML files the WEB, though UCSD is "piping"
them from a database. (The EAD Retrospective Conversion Guidelines are
available at Berkeley).

Until XML blooms, that's about it for now.

I hope this contributes a little to the discussion.
