Use the tag system#

Tags allow you to organize your bookmarks and publications easier. In BibSonomy you also can use tags as a keyword for searching and comparing items.

How does the tag system work?#

From your computer or in real life, you probably know the opportunity to store files/documents in folders and subfolders. A file is placed in a specific folder.
The keyword system works in a completely different way. You can add as many tags as you want to a file/publication. That way you can find all files about a specific topic very fast and easily, for you only have to search for the corresponding tag. The advantage of the tag system is the fact that you can combine different tags when searching to achieve precise and specific results. For example, if you're looking for literature about the topic "politics in France", you can search with both tags "politics" AND "France". As a result, you get all articles that deal with both topics.
With this function, BibSonomy makes it easy for you to store, manage and share your literature with others.

TIP: Good tags are short and concise. In addition, we recommend to always use singular words (e.g. use tree instead of trees - or even better: use two keywords: tree AND forest), thus avoiding unnecessary word forms. If you want to use a tag that consists of two words (e.g. Computer Science) you should use PascalCase (e.g. ComputerScience).

System tags#

System tags are special tags that come with a predefined meaning. At present, BibSonomy offers three types of system tags:

Executable system tags#

Executable system tags are added to a post to execute some special action with that post.
  • for:<groupname>: Tagging a post with for:xygroup will copy that post to the group's collection with the tag replaced by from:YourUserName. Should you change or even delete your post, the copied post of the group will remain unaltered. You must be a member of the group you forward the post to.
  • send:<username>: This tag allows sending a post to the inbox of another BibSonomy user. To use this tag, the receiver must have added you to his friends list or you must be a member of the same group.

Meta system tags#

Meta system tags are used to label your posts. Currently BibSonomy supports the following meta system tags:
  • myown: A post tagged with myown will appear on your CV page.
  • sys:relevantFor:<groupname>: A post with the tag sys:relevantFor:xygroup will appear on the "relevantFor"-page of the xygroup. Thus, this tag has the same effect as selecting xygroup in the "relevant for"-box while editing the post.
  • sys:hidden:<tag>: hides a tag from every user besides yourself.

Search system tags#

Search system tags are not for tagging a post but rather to be used as a filter in search queries. They all have the same syntax: sys:<fieldname><fieldvalue>. For example, searching with sys:author:xyz will only return posts where the author is xyz. BibSonomy supports the following filters:
  • sys:author:<authorname> filters the search range by author.
  • sys:bibtexkey:<bibtexkey> filters the search range by bibtexkey.
  • sys:entrytype:<entrytype> filters the search range by entry type.
  • sys:group:<group> filters the search range by group.
  • sys:not:<tag> excludes entries with the tag <tag>. Here you can also use wildcards, e.g. sys:not:news_* excludes all posts with tags that start with news_.
  • sys:title:<title> filters the search range by title.
  • sys:user:<user> filters the search range by user.
  • sys:year:<year> filters the search by year. Several arguments are possible, e.g.:
    • 2000: all posts from the year 2000
    • 2000-: all posts from the year 2000 or from one of the following years
    • -2000: all posts from the year 2000 or from an earlier year
    • 1990-2000: all posts from the years 1990 to 2000
