In order to get external links to work, it seems necessary to make the following
additions to the attributes of the parameter entity % a.ext.ptr (declared on line
727 of eadbase.ent:
doc ENTITY #IMPLIED
from CDATA "ROOT"
to CDATA "DITTO"
( these have been lifted from the TEI extended pointer declaration, where they
perform the required function)
In the following example the <?TAGLINK ...> is required for Panorama.
<!DOCTYPE EAD PUBLIC "-//Society of American Archivists//DTD ead.dtd
(Encoded Archival Description (EAD))//EN" [
<!ENTITY pap SYSTEM "../ddc/dcdpap.sgm" NDATA SGML>
<?TAGLINK EXTREF "TEI-P3">
<extref doc="pap">this will link to the entire document, i.e. open it and place you
at the start</extref>
<extref doc="pap" from="ID(h-34)">this will open the document and take you to
the element with an ID of h-34</extref>
the to attribute can be used to delimit the close of the portion of the document
being linked to.
The script required to perform this in Dynatext is as follows:
I don't know if this will resolve all the problems that have been encountered with
external links, but it seems to have worked for some of those I have already
