Upload data to the Data Library through Ingrid scripts


The IRI Data Library is built on Ingrid, a PostScript-based language, that facilitates the creation of user-tailored analyses and graphics.
In this post describes the basic steps of adding data set to the data library through the ingrid script.

Can use any kind of text editor, 
in Windows - eg: Notepad, WordPad, ...
in Linux - eg: Emacs, vi editor, ... 

As an example:
Steps to add Tea production and Area to the Data Library.

Step 1. 

\begin{ingrid}
Scripts should write inside this codes.
\end{ingrid}

Step 2. 
\begin{ingrid}

    /tea insertdataset:

    The data set and all the other commands are inside this codes.
  
    :insertdataset

\end{ingrid}

Inserting grid

grid:
      /name /T def
      /long_name /Time def
      monthtime
      1
       Jul 1867 ensotime
       12 1
         Jul 2016 ensotime
         :grid

This is an example of create a Time grid.
Words with backslash sign(/) describes words that added by users(new words), should end with def.
monthtime, ensotime are some key words that describe the format of the date.
This grid describe Years from 1867 to 2016.

Add a Variable and relative Data

variable:
     /name /area def
     /units /Extent ha def
     /missing_value -9999 def

     grids: T :grids

     values:  :values

     :variable

This shows how to define variable called area. 
Units of the area is Extent Hectares.
Missing values(values that not entered) display by -9999.
This area values appears with the Year. Added the grid called T.

values:
Inside this codes enter the area data from 1867 to 2016
 :values

As mentioned above we can add more than one variable in a one script.

Example:

After edit the text, need to save the files as .tex extension.
Commonly files added as index.tex. 

Step 3. Finally add the files to the Data Library. 
Now the above insert data displays as---> Link

Location to store data In order to add data to a data library first user needs to identify where we going to store the data.  where do we store our Ingrid script? file system \local \Data \Data catalog \entries \SL \FECT where do we store data files? file system \local \Data \ SL\ FECT In the above-mentioned location, the user should create a folder under the user's name.  Create a script to add data The example code can find in this path which have create under the above-mentioned location Folder Path: /local/data/DataCatalog/entries/SL/FECT/MOH/District_DengueCase Below is an example to create a district-wise dengue cases map for Sri Lanka .
