Despite being very different projects Wikidata and OpenStreetmap have a number of similarities. Recurring patterns in how they organise and support the work of their communities. We documented a number of these patterns in the ODI Collaborative Maintenance Guidebook. There were also a number we didn't get time to write-up. A further pattern which I … Continue reading Schema explorers and how they can help guide adoption of common standards
This is a post about building tools to validate data. I wanted to share a few reflections based on helping to design and build a few different public and private tools, as well as my experience as a user. I like using data validators to check my homework. I've been using a few different recently … Continue reading Building data validators
OpenActive is a community-led initiative in the sport and physical activity sector in England. It's goal is to help to get people healthier and more active by making its easier for people to find information about activities and events happening in their area. Publishing open data about opportunities to be active is a key part … Continue reading Some lessons learned from building standards around Schema.org
GDS have published some guidance about publishing reference data for reuse across government. I've had a read and it contains a good set of recommendations. But some of them could be clearer. And I feel like some important areas aren't covered. So I thought I'd write this post to capture my feedback. Like the original … Continue reading 12 ways to improve the GDS guidance on reference data publishing
For the past month I've been working on a small side project which I'm pleased to launch for Open Data Day 2021. I've long been a fan of OpenStreetMap. I've contributed to the map, coordinated a local crowd-mapping project and used OSM tiles to help build web based maps. But I've only done a small … Continue reading OSM Queries
One of my little side projects is to explore historical images and maps of Bath and the surrounding areas. I like understanding the contrast between how Bath used to look and how it is today. It's grown and changed a huge amount over the years. It gives me a strong sense of place and history. … Continue reading Bath Historical Images
In my last post I explored how we might better support the use of datasets. To do that I applied the BASEDEF framework to outline the ways in which communities might collaborate to help unlock more value from individual datasets. But what if we changed our focus from supporting discovery and use of datasets and … Continue reading Cooking up a new approach to supporting purposeful use of data
Getting the most value from data, whilst minimising its harmful impacts, is a community activity. Datasets need to be governed and published well. Most of that responsibility falls on the data publisher. Because the choices they make shapes data ecosystems. But other people have a role to play too. Being a good data user means … Continue reading How can you help support the use of a dataset?
Change discovery is the process of identifying changes to a resource. For example, that a document has been updated. Or, in the case of a dataset, whether some part of the data has been amended, e.g. to add data, fill in missing values, or correct existing data. If we can identify that changes have been … Continue reading Why is change discovery important for open data?
Last month I wrote a post looking at how publishing new data might increase the value of existing data. I ended up listing seven different ways including things like improving validation, increasing coverage, supporting the ability to link together datasets, etc. But that post only looked at half of the issue. What about the opposite? … Continue reading How can publishing more data decrease the value of existing data?
