69 | # The user will usually be instantiating a Tradition object, and |
70 | # examining its collation. The information about the tradition can |
71 | # come via several routes: |
72 | # - graphML from CollateX or elsewhere, standalone |
73 | # - TEI parallel segmentation |
74 | # - Leuven-style spreadsheet of variants, converted to CSV, plus base text |
75 | # - apparatus pulled from CTE, plus base text |
76 | # From this we should be able to get basic witness information. |
77 | # |
78 | # Alternatively the user can just give us the uncollated texts. Then |
79 | # instead of passing a collation, s/he is passing a set of witnesses |
80 | # from which we will generate a collation. Those witnesses can be in |
81 | # plaintext or in TEI with certain constraints adopted. |
82 | |
83 | # So the constructor for a tradition needs to take one of these infosets, |
84 | # and construct the collation and the witness objects. |
