1. Text image linking IDE Spring School 2015, Graz

2. TEI document (i.e. text) model element TEI { ( teiHeader, ( ( model.resourceLike+, text? ) | text ) ) } Members of model.resourceLike are: facsimile fsdDecl sourceDoc Folie 2 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz

3. Facsimile Images <facsimile> <graphic url="page1.png"/> <graphic url="page2.png"/> <graphic url="page3.png"/> <graphic url="page4.png"/> </facsimile> [A series of images, referenced by <graphic>, e.g. pages of a book.] Alternative: <media mimeType="image/png" url="page1.png"/> Folie 3 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz

4. Facsimile Identify images <facsimile> <graphic xml:id="page_1" url="page1.png"/> <graphic xml:id="page_2" url="page2.png"/> <graphic xml:id="page_3" url="page3.png"/> <graphic xml:id="page_4" url="page4.png"/> </facsimile> [A series of referenceable images, identified by @xml:id.] Folie 4 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz

5. Reference identified images <text> <pb facs="page1.png"/> <!-- text contained on page 1 is encoded here --> <pb facs="page2.png"/> <!-- text contained on page 2 is encoded here --> </text> Global attribute @facs (if module transcr is loaded) Discussion whether milestone elements mark the beginning or the end of a span of text is settled put them at the beginning! Find the mistake! Folie 5 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz

6. Reference identified images <text> <pb facs="page1.png"/> <!-- text contained on page 1 is encoded here --> <pb facs="page2.png"/> <!-- text contained on page 2 is encoded here --> </text> These are the names of the images, not the values of @xml:id!

7. Facsimile Group images <facsimile> <graphic url="page1.png"/> <surface> <graphic url="page2-highRes.png"/> <graphic url="page2-lowRes.png"/> </surface> <graphic url="page3.png"/> <graphic url="page4.png"/> </facsimile> [<surface> might be used to group images that show the same surface.] Folie 7 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz

8. Facsimile Group groups of images <facsimile> <surfaceGrp n="leaf1"> <surface> <graphic url="page1.png"/> </surface> <surface> <graphic url="page2-highRes.png"/> <graphic url="page2-lowRes.png"/> </surface> </surfaceGrp> </facsimile> [<surfaceGrp> might be used to group surfaces i.e. to represent leafs.] Folie 8 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz

9. TEI vs. other formats This TEI markup might be used to document the whole file structure of a project, e.g. images in different resolutions. This is still the file level! There are other formats out there to achieve the same and maybe better, e.g. METS (Metadata Encoding and Transmission Standard) HAB Digital library uses METS e.g. http://diglib.hab.de/edoc/ed000086/mets.xml Folie 9 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz

10. Ambiguous TEI The examples using <facsimile> with <surface> are ambiguous: On one hand <facsimile> contains a representation of some written source in the form of a set of images rather than as transcribed or encoded text. On the other had <surface> defines a written surface as a two-dimensional coordinate space, optionally grouping one or more graphic representations of that space, zones of interest within that space, and transcriptions of the writing within them. Folie 10 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz

11. surface Contained by transcr: facsimile sourceDoc surface surfaceGrp zone @attachment describes the method by which this surface is or was connected to the main surface Sample values include: 1] glued; 2] pinned; 3] sewn @flipping indicates whether the surface is attached and folded in such a way as to provide two writing surfaces att.coordinated (@ulx, @uly, @lrx, @lry, ) Folie 11 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz

12. zone defines any two-dimensional area within a surface element. @rotate indicates the amount by which this zone has been rotated clockwise [ ]. The orientation is expressed in arc degrees. att.coordinated (@ulx, @uly, @lrx, @lry, ) Folie 12 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz

13. Beware The coordinates stored in the attributes (@ulx, @uly, @lrx, @lry, ) are taken from an image with a certain resolution! If you use multiple images with different resolutions in your webpage you will have to calculate the actual coordinates of a zone in the image shown.

14. Oxygen TEI-Facsimile-Plugin https://github.com/oxygenxml/TEI-Facsimile-Plugin How to install it Unzip builds/addon/image-markup-plugin-1.0.0-SNAPSHOT-plugin.zip inside {OxygenInstallDir}/plugins/ After installing it, you should see an Image Markup Sample button on the toolbar. Click it to launch a sample file and to initialize the Image-Markup view with an image. If you right click on a rectangle in image view, you can either delete it (and will reflect in the editor) or copy it. You can use the mouse to draw a new rectangle over the image. Then right click and copy its coordinates to paste them in the editor. Folie 14 Scha an - TEI in detail - Text image linking IDE Spring School 2015, Graz
