 A `.janno` file is a tabular, tab-separated (`.tsv`) file. A base set of `.janno` file columns are specified in the Poseidon package specification [here](https://github.com/poseidon-framework/poseidon-schema/blob/master/janno_columns.tsv), including information on which columns are mandatory, which ones are list columns that can hold multiple entries, and which ones limit the allowed set of entries to a strict enumeration. Beyond that the `.janno` file can include any number and type of additional columns to hold project- and context-specific variables. These arbitrary additional columns should be named in a way so that they do not conflict with the base set. They are not validated (assumed to free-form text) by the Poseidon tooling, but they will be preserved in the Poseidon package, and propagated in operations like `trident forge`.
 
-The following documentation includes additional background information ob the base set. This should make it more easy to understand and use the columns for both published and unpublished data. A `.pdf` version of the latest version of this document is available for download [here](https://github.com/poseidon-framework/poseidon-framework.github.io/blob/master/janno_details.pdf).

 While previous versions of the `.janno` base set included various explicit `_Note` columns to add free form information to specific columns or column blocks, from Poseidon v3.0.0 onwards these explicit columns were removed. The schema supports arbitrary additional columns, so the user can add ANY `_Note` column they deem relevant or useful. The Poseidon tooling, e.g. the `trident` CLI software, still gives special considerations to columns with the `_Note` suffix when sorting columns. For example a column `Relation_Note` will be appended after all other `Relation_*` columns, but a more specific `Relation_Degree_Note` right after `Relation_Degree`.
