README.md

VisColl is for building models of the physical collation of manuscripts, and then visualizing them in various ways. The VisColl project is led by Dot Porter at the Schoenberg Institute for Manuscript Studies at the University of Pennsylvania, in collaboration with the University of Toronto Libraries and the Old Books New Science lab. Collaborators include Alexandra Gillespie, Alberto Campagnolo, and Conal Tuohy.

The core of VisColl is the data model, which is described below. There is a schema and example data models in the data section of this repo. The Collation Modeler and Collation Visualization described here are SIMS-developed implementations, and serve as proof of concept for the project. For more information on the VisColl web application, currently under development at the University of Toronto through the Digital Tools for Manuscript Study project, visit the website here.

VisColl is free and available for anyone to use.

If you do use VisColl to build collation models or visualizations of manuscripts, please cite your use in the following format:

This visualization was created using VisColl (https://github.com/leoba/VisColl) on [Date]

VisColl involves three steps:

  1. Create a Collation Model
  2. Create an Image List
  3. Generate a Collation Visualization (see http://dorpdev.library.upenn.edu/collation/ for some examples of what the Collation Visualization looks like)

Create a Collation Model

To create a collation model, use the Collation Modeler form (currently at http://tinyurl.com/CollModel/ and described at https://github.com/demery/collation-modeling)

Export the Leaves XML from the Collation Modeler.

Create an Image List

In addition to the Leaves XML file, you will also need to have a file listing URLs to images, matched with the folio or page number for those images.

The simplest way to create this file is using Excel. First, create a spreadsheet with folio or page numbers in the first column, and the corresponding image URL in the second column (do not include column headings). For example:

1r http://project.org/image1r.jpg

1v http://project.org/image1v.jpg

2r http://project.org/image2r.jpg

2v http://project.org/image2v.jpg

If you are using manuscripts from OPenn, you can use the template spreadsheet here to build your image list using Excel: https://github.com/leoba/VisColl/blob/master/data/OPenn_imagelist_template.xlsx. Follow the instructions on the first tab.

Then save this file as an XML file in Excel (Save As -> Excel 2004 XML Spreadsheet). As of right now, the image list file must be named according to the shelfmark in the Collation Modeler, but with all spaces removed. So for a Collation Modeler form with the shelfmark Cotton MS Claudius B IV, the image list file would be called:

CottonMSClaudiusBIV-imageList.xml

If the image list is named incorrectly, the process won't work correctly.

Generate Collation Visualization

To generate a Collation Visualization, go here: http://138.197.87.173:8080/xproc-z/visualize-collation/ (please email dorp@upenn.edu if the Collation Visualizer is not working)

Load the Collation Model and the Image List where indicated.

Click "Submit". In a few moments, you will be asked to download a .zip file containing the full Collation Visualization (in HTML). There will be one HTML file for each quire, plus a folder of supporting materials. You will need to keep everything together in order for it to work.

NOTE: Some computers are downloading the .zip file in which the file name is surrounded by single quotes (i.e., literally, 'VisColl.zip'). Your computer will not recognize the .zip' file extension and will be unable to open this file. You will need to edit the file name and remove the single quotes. Once you do this, your computer will recognize the file type and will be able to open it. So, if your computer can't open the file after downloading, check to see if it has single quotes around it.

The Collation Visualization online tool uses XProc-Z, developed by Conal Tuohy and available at his github: https://github.com/Conal-Tuohy/XProc-Z

Many thanks to Conal for incorporating the XSLT files found in this repository into the XProc pipeline that runs as Collation Visualization.

Generate Collation Formula

To generate a collation formula, process the xslts/generate_formula.xslt file against the Leaves XML file. On a Mac, using the Terminal, your command will look something like this:

saxon Cotton_MS_Claudius_B_IV.xml xslts/generate-formula.xsl

The output will be an HTML file, with the same name as your input file, containing two different collation formulas.

If you have a preferred formula and you would like to see it added to the output for generate-formula.xsl, please feel free to edit that file, or contact me and I will add it.
