Graphics (and other media)

Background

While audio and video are not used often at the moment, images are widespread in Brill MRWs.

Guidelines

See the TEI Guidelines Chapter 3.9 Graphics and Other Non-textual Components.

Explanation

Images in Brill MRWs often have information "baked in" so often the caption is not so much a concern as is the position, size, image quality, and whether it should be displayed in a lightbox ("pop-up"). Remember that the image itself – that is, a jpeg or mp3 file – is not stored in the XML, only a link to the file is.

In TEI, <figure> is the main element. It can contain <head> and <figDesc> elements for the caption and such information. Nested within is a <graphic> element and/or a <media> element. Brill uses these elements to indicate the location of the media file, with the @url attribute. (It is also possible, but not recommended, to place a <desc> in <graphic> and <media>). In the case of audio or video, Brill adds a @mimeType attribute to <media>, with value such as "audio/mp3" or "audio/wav". <graph> and <media> can take @width, @height, and @scale attributes to set display preferences. The lightbox function is triggered by a @style attribute with the value "display:popup". Unfortunately, this is not a correct CSS property-pair, but there is no other way.

Example

<figure>
    <graphic url="bdr-vol1-p-109" style="display:pop-up"></graphic>
    <head>Grave Desecration Villaret</head>
    <figDesc>During the night of May 17, 1990, all of the graves were desecrated in the little Jewish cemetery of the Swiss village of Villaret.</figDesc>
</figure>

Scholarly Editions

For publication of online images on SE, do as follows:

  1. Check if images files have the correct names and formats
  2. Place the images on O:\ which is Brill's iiif service (images will be uploaded to the iiif server)
  3. Check if @url in the CTS compliant TEI XML has the correct value

The correct value is https://iiif.arkyves.org/image.jpg/full/500,/0/default.jpg

For example https://iiif.arkyves.org/LC2020_LHOM_01edition_RGB_L.jpg/full/500,/0/default.jpg

The "500" parameter sets the image width (relative to its full size). Replace "500," by "full" if you want to render the complete image.

Naming Conventions

Name the images as follows: textgroup.work.version followed by the extension

Formats

Allowed formats are .jpg and .pgn.

Other images

For images that are not inline (i.e, in the text), e.g. cover images in the Library (textgroup, work, version), edit the XM in the CTS files.

For example

<ti:work xmlns:cpt="http://purl.org/capitains/ns/1.0#"
   xmlns:saws="http://purl.org/saws/ontology#"
   xmlns:dc="http://purl.org/dc/elements/1.1/"

   </cpt:structured-metadata>
   <!-- this is the cover image for the version -->
  </ti:edition>
  <cpt:structured-metadata>
      <scaife:image>https://iiif.arkyves.org/LC2020_LHOM_unit_RGB_L.jpg/full/full/0/default.jpg</scaife:image>
      </cpt:structured-metadata>
      <!-- this is the cover image for the text group -->
</ti:work>

!! not sure how to get an image for the work?? !!

Recommendation

  1. Use @type to distinguish (the presently undistinguished) different types of figures, such as illustrations, maps, or character images.

  2. Similarly, distinguish different types of caption, using <head> for the name of the figure and <figDesc> for a description of the representation.

  3. Images are a bit of an undeveloped area in MRWs. Redefine things like size, position, buttons, etc.
