S Some agencies provide raw data through text files, Excel
sheets and or API
S Examples: MSHA, BLS, OSHA, ETA, VETS, WHD, OPA
S Current API*
S Covers over 200 datasets.
S Created by OPA Division of Enterprise Communications.
S Sole mission is to provide developers with access to DOL
S api.dol.gov currently runs on Windows 2008.
*The current API is often referred to as APIv1 or “the legacy API
S Built using OData.
S Solution also
S Software development
kits - not required, but
S Department of Labor (DOL) data primarily available at:
S DOL’s developer site
S Career One Stop
S AJC locations; licensing, certification, education,
apprenticeship, community college and training info; job
listings and job count info.
S Occupational Information Network (O*NET)
S Detailed profiles of occupations; translations from military
occupations, profiles of interests

S Click the Register link.
S Fill in the registration form and submit it.
S A confirmation email will be sent to the
address you provided during registration.
S Click on the link in the email to activate
your developer account.
S Create API Key (Token)
S Visit https://devtools.dol.gov/developer
S At the login page, enter your username
S Click on the My Tokens link
S Click "Create New Token"
S Provide a Shared Secret (deprecated, but
for the moment still required for the
registration process), Application Name,
and a Description
S The token value will be auto-generated
and added to your tokens list.
S Access the API
S The API is exposed as an OData
producer, with the addition of
S To make API calls you must
supply a valid Token as the
"KEY" parameter on the query
string with every request.
For DOLAgency and token d9c6c290-
direct link to Agency data is:
By default, the DOL API's responses
are in XML format. To receive the data
in JSON, send an "Accept" header
S A lot of the assets are utilizing APIv1.
S Some are using their own API standard.
S By Q4 2015, all (participating) agencies will move to
APIv2 Desired Features
1. Single sign-on and authentication for datasets with private or
2. Improved readability and usability of dataset documentation for all
skill levels of developers.
3. Create Internal API with legacy functions, plus CRUD and account
4. Modifying External API and SDKs to facilitate end-user development.
5. Enable all open data that is available via the API to be available in
one of the accepted bulk downloadable formats with options for
6. Update Token self-service app to integrate with APIv2, mobile
support and new datasets.
7. Expose DOL web content as structured data via the API.
APIv2 is backwards-compatible with APIv1
APIv2 High Level Requirements
S Support requests over SSL/TLS
S Support read/write transactions (it is currently read-only)
S Continue to require and support API Keys
S Continue to be a centralized API
S Should not break existing apps using the DOL API
S Support the myUSA (if available or equivalent) authentication
S Continue to be a RESTful service that supports all platforms
S Same codebase for internal and external deployments
S Conform to the 18F API standards to the highest degree
S Based on the GitHub - Project Open
Data community contributed code
S Will run on the LAMP stack.
S Will also consist of:
S Code Igniter (Ellis Lab) Application
S Server Clustering using a Beowulf Cluster
to leverage load balancing and parallel
S Caching using Varnish Cache
S Will incorporate Object Oriented
S Results default to JSON
