The dj_mapper.py python script converts Dow Jones Watch list files to json files ready to load into Senzing. This includes the following databases ...
- Risk and Compliance database (PFA)
- High Risk File or (HRF)
- Adverse Media Entities (AME)
- State owned companies (SOC) format not supported!
- Trifecta (includes PFA, AME and SOC)
If you subscribe to any of these Dow Jones feeds, you will have instructions from them on how to login and download monthly or daily files. The idea is that you periodically refresh their full file and perform daily updates on top of it.
Trifecta Notes:
- If you download the Trifecta file, there is no need to download and map the individual files it contains.
- Since the standalone SOC format is not supported, the Trifecta file is the only way to map and load it into Senzing.
- Since the mapper only allows one data source code per file, you can specify "-d DJ-PFA" on the command line. If you want to use another code that is fine, but you will need to register it in the dj_config_updates.json file.
- Since the Trifecta file does not include the HRF file, you must map and load that separately if you want it.
Loading Dow Jones data into Senzing requires additional features and configurations. These are contained in the dj_config_updates.json file.
Usage:

-i INPUT_FILE, --input_file INPUT_FILE
A Dow Jones xml file for PFA or HRF.
-o OUTPUT_FILE, --output_file OUTPUT_FILE

.json extension.
-l LOG_FILE, --log_file LOG_FILE
optional statistics filename (json format).
-d DATA_SOURCE, --data_source DATA_SOURCE
please use DJ-PFA, DJ-HRF or DJ-AME based on the type of file.

styles: 0=None, 1=Legacy linking, 2=Pointers (new for
Senzing v1.15)
-e, --extended_format
include profile notes, sources, and images- Prerequisites
- Installation
- Configuring Senzing
- Running the mapper
- Loading into Senzing
- Mapping other data sources
- python 3.6 or higher
- Senzing API version 1.13 or higher
- Senzing/mapper-base
Place the the following files on a directory of your choice ...
Note: Since the mapper-base project referenced above is required by this mapper, it is necessary to place them in a common directory structure like so ...
/senzing/mappers/mapper-base
/senzing/mappers/mapper-dowjones <--You will also need to set the PYTHONPATH to where the base mapper is as follows ... (assumuing the directory structure above)
export PYTHONPATH=$PYTHONPATH:/senzing/mappers/mapper-baseNote: This only needs to be performed one time! In fact you may want to add these configuration updates to a master configuration file for all your data sources.
From the /opt/senzing/g2/python directory ...
python3 G2ConfigTool.py <path-to-file>/dj_config_updates.jsonThis will step you through the process of adding the data sources, entity types, features, attributes and other settings needed to load this watch list data into Senzing. After each command you will see a status message saying "success" or "already exists". For instance, if you run the script twice, the second time through they will all say "already exists" which is OK.
see dj_config_updates.json for a list of configuration updates required.
First, download the xml file you want to load from the DowJones website. Here are a couple of examples of how the files will be named ...
- PFA2_201902282200_F.xml <--Risk and Compliance database (PFA)
- DJRC_HRF_XML_201903012359_F.xml <--High Risk File (HRF)
- DJRC_AMe_XML_201903012359_F.xml <--Adversse Media Entity (AME)
It is good practice to keep a history of these files on a directory where you will store other source data files loaded into Senzing.
Second, run the mapper. Example usage:
python3 dj_mapper.py -i ./input/PFA2_201303312200_F.xml -o ./output/PFA2_201303312200_F.json -l pfa_stats.jsonThe output file defaults to the same name and location as the input file and a .json extension is added.
-
Add the -d parameter if you get a message that the data source could not be determined from the file name.
-
Add the -e parameter if you want to include the following fields: profile notes, sources, and images.
-
Add the -r 1 parameter if you are on Senzing versions prior to v1.15.
Note The log file should be reviewed occasionally to determine if there are other values that can be mapped to new features. Check the "UNKNOWN" section for values that you may get from other data sources that you would like to make into features. Most of these values were not mapped because there just aren't enough of them to matter and/or you are not likely to get them from any other data sources. However, DUNS_NUMBER, LEI_NUMBER, and the other new features listed above were found by reviewing these statistics!
If you use the G2Loader program to load your data, from the /opt/senzing/g2/python directory ...
python3 G2Loader.py -f /mapper_dowjones/output/PFA2_201902282200_F.jsonThe PFA data set currently contains about 2.4 million records and make take a few hours to load depending on your harware. The HRF data set only contains about 70k records and loads in a few minutes.
If you use the API directly, then you just need to perform an process() or addRecord() for each line of the file.
Watch lists are harder to match simply because often the only data they contain that matches your other data sources are name, partial date of birth, and citizenship or nationality. Complete address or identifier matches are possible but more rare. Likewise, employer names and other group affiliations can also help match watch lists. Look for and map these features in your source data ...
- CITIZENSHIP
- NATIONALITY
- ADDRESS_COUNTRY in addresses
- PASSPORT_COUNTRY and other identifier countries
- GROUP_ASSOCIATION_ORG_NAME (employers and other group affiliations)
