Tagging image metadata inside a facsimile element #9

Open HugoSchtr opened 2 years ago

HugoSchtr commented 2 years ago

Image metadata is currently tagged within the <sourceDoc> element with <graphic>. 

<sourceDoc>
      <graphic url="FRAN_0025_3056_L-0.jpg" width="2894px" height="4393px"/>
      <surfaceGrp>
         <surface xml:id="eSc_textblock_afbab800"
                  type="structure_{type:col_1;}"
                  points="421,615 421,2236 465,2211 465,2266 421,2269 425,2449 410,4148 362,4213 205,4228 234,615">
            <zone xml:id="eSc_line_86b00a8e"
                  type="mask"
                  points="285,838 293,812 322,798 380,801 377,863 289,874">
               <path type="baseline" points="289,841 389,845"/>
               <line>198</line>
            </zone>
            ...

Instead, and for the sake of clarity, image metadata can be tagged inside the <facsimile> element: 

<facsimile>
      <graphic url="FRAN_0025_3056_L-0.jpg" width="2894px" height="4393px" xml:id="FRAN_0025_3056_L-0"/>
</facsimile>
<sourceDoc>
      <surfaceGrp facs="#FRAN_0025_3056_L-0">
         <surface xml:id="eSc_textblock_afbab800"
                  type="structure_{type:col_1;}"
                  points="421,615 421,2236 465,2211 465,2266 421,2269 425,2449 410,4148 362,4213 205,4228 234,615">
            <zone xml:id="eSc_line_86b00a8e"
                  type="mask"
                  points="285,838 293,812 322,798 380,801 377,863 289,874">
               <path type="baseline" points="289,841 389,845"/>
               <line>198</line>
            </zone>
            ...

Image metadata and transcription data would then be separated in their respective elements. With appropriate xml:id and facs attributes, multiple images could be encoded with a single TEI file.

I would put <graphic> in <sourceDoc>, because in some cases you would need to use @source. The original image, may it be referenced in <graphic> or @source, would therefore be in the same element <sourceDoc> rather than sometimes in <sourceDoc>, sometimes in <facsimile>. No? Cf.
