Planning data design

Advisory group

MHCLG Digital Planning are developing a set of open, reusable data specifications to underpin planning applications. These will make sure the current templates are underpinned by data.

The specifications will define the structure and format of data that is required when submitting a planning application based on the national legislation in place.

Our intended outcomes are to:

• improve interoperability, accessibility and understanding
• enable integration with existing datasets (for example land use, and infrastructure)​
• foster collaboration among government bodies, developers, planners, software providers​ and everyone else
• improve data flow, quality, consistency and transparency in the planning process

We have a challenging timeline to deliver specifications by the end of March 2025. In order for this to be feasible we are aiming for the minimum viable specifications that underpin the current national system.

We are doing this work in the open. To help us we brought together 2 groups:

• Advisory group - this group consists of a mix of people from industry including software providers, government bodies, LPAs and other interest groups
• Community group - this group consists of everyone else interested in planning applications and the work we are doing to develop data standards, and is open to all LPAs

What's next

We have taken feedback from our advisory group and community and developed a repository of the issues and questions that we have. We are going to work through these issues offline over the next month.

Our next advisory group meeting and drop in session will be focused on closing as many issues as we can to enable us to develop the data models.

The session will be held on

TBC - we have asked for comments and feedback on the specifications by 16 May.

Updates

Week beginning 14 Apr

• We published a blog post covering the recent events and summarising how we got to this point with the draft specifications.
• We've confirmed we are looking for the initial round of feedback on the draft specifications by 16 May.

Week beginning 7 Apr

• We've updated the "index" specification file to include all the codelists.
• Updated the application specification to include an expanded file sub-structure (see issue #229).
• Added a uprns[] field to the Site details module (see issue #8)

Week beginning 31 Mar

• We've added a few more issues based on comments from the advisory and community sessions.
• We ran a session with a group of local planning authorities and suppliers about how they can help us test the specifications
• We published an index specification file that includes all the modules and codelists covering all application types

Week beginning 24 Mar

• We published a "compiled" specification for each application type and sub type.
• We held the advisory group session on the 27th March (slides, minutes)
• We held a community drop-in session on the 28th March (slides, video)

Week beginning 17 Mar

• We have been grouping the issues into issues we can close right now, issues that need policy input and issues that we are parking for a later iteration
• We have set up a discussion thread per application type - each discussion lists the components needed for the application type

Week beginning 10 Mar

• We arranged the next sessions - these will be on the 27th and 28th of March and we will be presenting the first drafts of the specifications.
• We have published a discussion for each of the codelists we need to support the specifications

Week beginning 3 Mar

• We held a drop-in session on Wednesday 5 March (recording)
• We published the list of modules required for each application type, including sub-types where applicable.

Week beginning 24 Feb

• We held an advisory group session on 26 Feb where we discussed numerous open issues (slides, minutes)
• We finished an initial draft of an information model for each module/component.
• We identified more codelists that are required to support completing an application. There is a discussion for each one.

Week beginning 17 Feb

• We have prepared a lean coffee style workshop for the next advisory group session.
• We have created a first draft of the information models for each component
• We have learnt that in some cases the application type isn't the only piece of information needed to determine what modules are required (see issue #158)
• We have started setting out the codelists needed to support the planning application specification.

Week beginning 10 Feb

• We added a Notification of proposed works to trees in a conservation area application type to the list.
• We have been designing the next advisory group session where we’ll be working through the open issues and discussions in a lean coffee style workshop.
• We have started pulling together a list of planning requirements - the documents that applicants need to prepare along side their application. We opened an issue where we can continue discussing the planning requirements.
• We started drafting a set of information models for the modules needed for Householder applications.

Week beginning 3 Feb

• We add Hedgerow removal notices to the list of application types. We still need to confirm the modules for the application type (see issue #1)
• We published a list of the application forms we've looked at
• We published a list of the modules we are working through as data
• We proposed combining the "Declaration" and "Declaration - trees" modules

Week beginning 27 Jan

• We held a community drop in on Wednesday 29 Jan (slides, video)
• Set the dates for the next sessions. Advisory group on 26 Feb. Community drop-in on 5th Mar.
• Continued adding to and working through the open issues. Thank you to all those that are contributing.
• Published the original list of application types we are working with. We will up this based on the currently open issues related to application types

Week beginning 20 Jan

• We held the second advisory group session (slides, minutes)
• We set up a dedicated repository for the Planning application data specification work. We will use this to publish work, such as supporting datasets and specification, as we progress.
• We have started converting the various questions and ideas we have received into individual issues that can be resolved one by one.
• We have set up a module tracker spreadsheet. We are using this to track progress on each of the individual modules. You can view this to follow along.

Week beginning 13 Jan

• Preparing for the next advisory session - will be held on 22 Jan 2025
• Reply to contributions on the discussion thread, specifically on different application types we could look at
• Exploring ways to manage issues openly
