Mapping MED stencils to HB stencils

File last modified
For other MEC files, see the MEC Index page.

The *.med file

The ##.med file is an ordered list of unique stencils extracted from volumes "##" of the MED, but otherwise left unchanged. Chunks corresponding to HB batches are cut out of it during the mapping process.

The *.map file

The *.map file (where *= the Hyperbib batch designation) is a permament record of HB stencils and the associated stencils found in the MED. It will be used:

To add matching ID and RID values to the equivalent stencils in HB and MED.
To replace most variant MED stencils with a canonical MED stencil based on the HB stencil.

The *.map file is a valid and parsable SGML file, employing the qc.dtd .

The *.map file contains consists of groups:

Each group contains one HB stencil (<hb>), followed by one canonical MED stencil (<mud>), followed by zero or more actual med stencils (<med>).

  <hb>...</hb>      = hyperbib stencil, as found in HB files.
  <mud>...</mud>    = canonical MED stencil, generated from the HB
                                  stencil and occasionally tweaked.
  <med>....</med>
  <med>....</med>
  <med>....</med>   = actual med stencils, as found in the MED files.

The canonical MED stencil differs from ordinary correct med stencils in two regards: the MS abbreviation has been tagged, using the <MS> element; and (unlike all volumes of the MED except U-end), it uses the <AUTHOR> element.
Not all HB stencils bear the same relationship with med stencils. Some represent the literal form that all the equivalent med stencils should take; some correspond to a number of different med stencils that differ only in their date; and some correspond with a number of med stencils that differ in other respects. As a result, not all med stencils will find an exact match in the bib. Aside from (a) the ones that will not be there at all (see below and the Guide to the Unmerged), which will be left unlinked on the first pass, and those (b) that will be essentially identical in bib and dictionary, some (c) should link to a "various-date" hb stencil that covers all possible dates under a single stencil, and some (d) should link to a blanket stencil that allows other elements of the stencil to vary beyond just the date.
Here are examples of the four kinds:
1. Leave unlinked and unreplaced in med; no match expected in hb: <med><STNCL> <DATE>(1482)</DATE> <TITLE>in Leadam Star Chamber Cases (1903) 9</TITLE> [OD col.]</STNCL></med>
2. Link and replace entire <med> stencil with <mud> stencil in med: <mud><STNCL><DATE>a1425</DATE> <TITLE>MChristi</TITLE> <MS>Arun 286</MS></STNCL></mud>
3. Link and replace all but date of med stencil with mud stencil in e-MED: <hb><STENCIL><DATE>(v.d.)</DATE><WORK>Paston </WORK><ABBR></ABBR></STENCIL></hb> <mud><STNCL><DATE>(v.d.)</DATE> <TITLE>Paston</TITLE></STNCL></mud> <med><STNCL><DATE>(1425)</DATE> <TITLE>Paston</TITLE></STNCL></med>
4. Link but leave entire <med> stencil intact in e-MED: <hb><STENCIL><DATE>v.d.</DATE><WORK>MS----- in Halliwell D. </WORK><ABBR></ABBR></STENCIL></hb> <mud><STNCL><DATE>v.d.</DATE><TITLE>MS-----</TITLE> in Halliwell <TITLE>D. </TITLE></STNCL></mud> <med><STNCL><DATE>(a1475)</DATE> <TITLE>MS Sln.1986</TITLE> in Halliwell <TITLE>D.</TITLE></STNCL></med>
Our solution to this resorts to different kinds of <grp> elements, each of which will be processed differently:
```
Type Action
----------------------------------------------------------------
(a) Leave these out of the .map file

(b) Place in <grp> med stencils that should be changed in 
 the dictionary to the canonical <mud> form 
 in its entirety, and linked to the hb stencil
 at the head of the group.

(c) Place in <prgrp> ("partial-replace groups") those med 
 stencil(s) that should be linked to the hb stencil at the head 
 of the group, and should be replaced in the dictionary by the 
 canonical form EXCEPT FOR THE DATE WHICH WILL BE LEFT INTACT, 
 AS FOUND IN THE MED TEXT. All "v.d." stencils should be put
 in <prgrp> (most will have already been assigned to 
 <prgrp>s automatically).

(d) Place in <nrgrp> ("no-replace groups") the med stencil(s) 
 that should be linked to the hb stencil at the head of the group, 
 but should NOT be replaced in the dictionary by the canonical form, 
 if any. Most or all HB stencils containing dashes ("-----") should
 be put in no-replace groups.
```

To perform the map, open the file of med stencils (say M1.med) and the corresponding map file (M1.map) in a text editor; open the same batch in Panorama; cut the mappable stencils from the med file and paste them into the map file under the corresponding <hb> and <MED> stencils. Use the panorama version to check notes and other details. Sample:

<!-- TITLE: Works -->
<!-- Preferred MS is WIN-C  -->
<grp>
<hb><STENCIL><DATE>(a1470)</DATE><WORK><AUTHOR SORT="Malory, Thomas">Malory</AUTHOR> <I>Wks.</I></WORK><ABBR>Win-C</ABBR></STENCIL></hb>
<mud><STNCL><DATE>(a1470)</DATE> <AUTHOR>Malory</AUTHOR> <TITLE>Wks.</TITLE><MS>Win-C</MS></STNCL></mud>
<med><STNCL><DATE>(1470)</DATE> Malory <TITLE>Wks.</TITLE></STNCL></med>
<med><STNCL><DATE>(a1470)</DATE> Malory <TITLE>Wks.</TITLE></STNCL></med>
<med><STNCL><DATE>(a1470)</DATE> <AUTHOR>Malory</AUTHOR> <TITLE>Wks.</TITLE>

MED stencils that fail to find an answering HB stencil in the appropriate HB batch should be left in the med stencils file, but marked by an initial letter to indicate why they failed to map:


Key to first-character-of-line codes attached to non-merging lines:

i=INCIPIT (incipit stencils from bib not yet available)
o=OD col (OD col stencils not included in bib)
p=PROBLEM (cannot determind the appropriate map with certainty)
m=at first look, apparently MISSING in hyperbib
s=only a SHORT STENCIL (or equiv.) is found in the Hyperbib; 
  needs full stencil in bib.

Include a note if it is not obvious why a stencil failed to merge, especially if it is marked "p"roblem. Like this:

s<med><STNCL><DATE>a1500</DATE> <TITLE>Med.Bk.(2)</TITLE> (Sln 3153)</STNCL></med>
s<med><STNCL><DATE>a1500</DATE> <TITLE>Med.Bk.(2)</TITLE> (Sln 405)</STNCL></med>


p<med><STNCL><DATE>a1425</DATE> *<TITLE>Medulla</TITLE> (Hrl 2270)</STNCL></med>
p<med><STNCL><DATE>a1500</DATE> *<TITLE>Medulla</TITLE> (Add 33534)</STNCL></med>
<!-- these two have wrong dates on 'em, prob. just errors -->

<med><STNCL><DATE>?c1460</DATE> <TITLE>Medulla</TITLE> (Way)</STNCL></med>
<!-- perh. this is unstarred ADD 33534 (i.e. ADD 33534:Way), but should prob. be checked -->

All files should be found (and replaced when done) in the netware space under \mec\assist\merge\[month]
