Mojo Facets - server side facet browsing using Mojolicious and jQuery UI


Data sources:

Put JSON file from Simile Exhibit project in data/ with extension .js or .json

Alternative format is pipe (|) separated text files with extension .txt
First column is always header with field names
Multi-line values should be wrapped in ^multi-line-text^

If you save bounch of html files with table in directory with .html extension, they will
we all read as single data set, allowing easy analysys of search results, for example.


Start with:

  LANG=hr_HR.utf8 ./script/mojo_facets daemon --reload


Data replication:

  # master
  ./script/mojo_facets daemon --listen 'http://*:4444' --reload

  # slave
  MASTER=http://localhost:4444 ./script/mojo_facets daemon --reload


Turning actions into changes:

There are two kinds of audit log in MojoFacets:

1. actions stored in /tmp/actions are clicks on user interface with parameters

2. changes are more structured, including old value and unique values from
   edit of one value in dataset

If you want to create changes which can be applied again on original dataset or
any other dataset which has same unique values you can use helper script:

  $ ./script/actions-to-changes /data/mojo_facets/*


Modify your data using perl snippets

Experimental REPL console supports perl snippets which get $row hash which is one
element from your dataset. All values are repetable, so you always have to create
array of values if you are creating new columns, even for single value.

* generate new columns with number of elements in some other column

  $row->{author_count} = [ $#{ $row->{autor} } + 1 ];

* generate century column from year

  foreach my $year ( @{ $row->{Year} } ) {
    push @{ $row->{century} }, int($year/100)+1;
  }

* modify existing column

  foreach ( @{ $rec->{'Cited Author'} } ) {
    s/^\.+//;
    $_ = uc $_; # assigment is needed to modify value!
  }

Code examples are stored in public/code

They use Column name.description.pl notatition so only snippets which have applicable
column will be shown.
