I don't like organising my bookmarks in directories because my bookmarks often belong to several categories. I use tags instead, that offer more flexibility.

I wanted to "see" my graph of tags and bookmarks.

In firefox, click on the bookmarks menu, then Show all bookmarks. In the new window, click on Import and Backup then Backup.... Choose where to put the file and you're done.

neo4j is a graph database management system. You can load a graph, query it and modify it.

Download neo4j and follow the installation instructions.

I use neo4j-community-3.0.4. I haven't tried other versions.

The script will delete all data from the database. Back up your existing database if you want to keep it.

Check your server config file to find the database location. The default is <NEO4J_LOC>/data/graph.db/. You can simply use cp -r or mv/ln -s to put it somewhere else.

• Make sure the server is not running when you move the files.
• The directory <NEO4J_LOC>/data/graph.db/ must exist. It can be empty.

Alternatively, see the neo4j-backup command.

<NEO4J_LOC>/bin/neo4j start

The script will connect to this running instance.

Requirements:

I use Python 3.5, py2neo 3.1.2 and json 2.0.9. I haven't tried different versions.

Run:

./load_bookmarks.py --input ~/Desktop/bookmarks-2017-01-01.json

./load_bookmarks.py --help

The graph you built has 3 types of nodes:

• bookmark
• tag
• container for the directory structure

containers and bookmarks are linked to their parent container. bookmarks are linked to their tags.

Open http://localhost:7474 in your favourite browser. If prompted for a user/password, try the default: neo4j/neo4j.

You are in the neo4j browser. You can enter queries (in cypher language) in the top banner with a $.

Try this for example: MATCH (n) RETURN n LIMIT 50. Click the play button on the upper right corner to execute the query, or press Enter or Ctrl+Enter.

I recommend styling the nodes and relationships to get the shape of the graph at a glance.

More on neo4j browser More on cypher query language

Get all the nodes:

MATCH (n) RETURN n

Note that by default the graph view shows all relationships between displayed nodes. So the query above will show your entire graph.

If you have lots of bookmarks, you can limit the number of returned nodes:

MATCH (n)
RETURN n
LIMIT 100

Get the root of the bookmark directory hierarchy:

MATCH (n:container {title:"ROOT"}) RETURN n

From there, double-click on nodes to get its neighbours.

See the bookmark directory hierarchy only, no bookmarks, no tags.

MATCH (c:container) RETURN c

Get the bookmarks and tags only, not directory.

MATCH (t:tag)--(b:bookmark) RETURN t,b

Bookmarks with no tags are not shown.

Get the bookmarks that don't have tags.

MATCH (b:bookmark)
WITH b, size((b)-->(:tag)) as degree
WHERE degree = 0
RETURN b

Get tags that are only used once

MATCH (t:tag)
WITH t, size((t)<--()) as degree
WHERE degree <= 1
RETURN t

See if there are 2 directories with the same name:

MATCH (c1:container), (c2:container)
WHERE c1.title = c2.title AND c1 <> c2
RETURN c1, c2

Get the tags and directories that share the same name.

MATCH (c:container), (t:tag)
WHERE c.title = t.name
RETURN c, t

Get the bookmarks tagged with NLP and the directories they live in.

MATCH (:tag {name:'NLP'}) <-- (b:bookmark) -[:has_parent*]->(c:container) RETURN b, c

Get the tags of bookmarks that are under my tech directory.

MATCH (:container {title:"ROOT"}) <-- (:container {title:""}) <-- (:container {title:"Bookmarks Menu"}) <-- (:container {title:"tech"}) <-[:has_parent*0..]- (:container) <-- (:bookmark) --> (t:tag) 
RETURN t

Probably quite a lot, given that:

• there's no tests!
• I've only tried with my own bookmarks, that I use in a peculiar way. All my bookmarks live in Bookmarks Menu. I don't use keywords,
