Maryland Open Data - Site Name Change

We wanted to follow-up about the exciting news related to Open Data in Maryland.

As has been advertised on the Open Data Portal for the last month, the Open Data Portal ( will be getting a new website address – The change to the new address is being done to better align the name of the site with the State’s open data initiative. Tonight (March 13th), the website address name will officially change. Access to the close to 1,300 open datasets will not change. Likewise the dataset names and ownership will not change. The only update necessary for those who view and visualize data on the portal will be changing any bookmarks that point to the Open Data Portal. Your username and password will remain the same. Those accessing the Open Data Portal using single sign-on within the Maryland domain, will not experience any changes. The link in your portal will direct you to the new address.

We have been reaching out to those users who are directly accessing the data on the portal using the dataset API, to inform them of the planned change. If you are currently accessing datasets on the Portal using the dataset API, you will need to update that API string in your application from 


The rest of the string, including the unique xxxx-xxxx at the end will remain the same. Unfortunately, this update to your API string cannot be applied until after 6 PM on March 13th. This is inclusive of custom applications and third party business intelligence platforms such as Microsoft Power BI, Tableau, Qlik, and others that are consuming data from the Open Data Portal.

As part of this update, the Maryland Council on Open Data’s website (currently located at will be accessed from the Open Data Portal. Any information about the Council on Open Data will be found at, by selecting the “Council on Open Data” link at the top of the page.

We are excited about this change as we believe we are better aligning the name of the site with the mission of the Open Data Program.

Again, the name change will take place at 6PM tonight (Wednesday, March 13). Please look to update your bookmarks and API strings after that time period.

If you have any questions at all or need assistance, please do not hesitate to reach out to​.
