Export for academicpages.github.io

[koppor]

The Jekyll template https://academicpages.github.io allows to create a nice academic page. Publications go into the folder https://github.com/academicpages/academicpages.github.io/tree/master/_publications.

JabRef should be able to create these markdown files.

Example: https://github.com/academicpages/academicpages.github.io/blob/master/_publications/2009-10-01-paper-title-number-1.md. Check the RAW file: https://github.com/academicpages/academicpages.github.io/blob/master/_publications/2009-10-01-paper-title-number-1.md?plain=1

Time stamp creation: Order by publication type (Book, Journal, book chapter, inproceedings, all-others).

Mapping

BibTeX	Markdown
title	title
-	collection always set to publications
-	permalink: to-be-done. Maybe citation key?
note	excerpt
date/year+month+day	date, use 01 if month or day do not exist
venue	booktile/journal (getFieldOrAlias, because it could be journaltitle
doi/url	paperurl
(all)	citation: Use current preview style (or do something short)
abstract	Text below the YAML in Markdown

I am not sure whether we hit limits of the current .layout-based exporter. Maybe, one needs to call the layouter for each bibentry separately?

Future work:

• support sub-grouping of inproceedings and all-others (e.g., workshops and conference articles should be distinguished. I personally do it via groups. Maybe a magic "Export" group. Details at Export markdown file containing all papers + links #468)
• help to solve Publication Categorization  academicpages/academicpages.github.io#48 and adapt the export accordingly.
• Export markdown file containing all papers + links #468
