Gemini 2.2 Profile for Geonetwork

Astun are pleased to announce that we’ve released our implementation of the Gemini 2.2 metadata profile as an official plugin for Geonetwork 3.0.x and later versions, and that it’s now available at the official Geonetwork metadata profile site metadata101.org.

So what does this mean?


It means that you can use Gemini 2.2 as a metadata standard within Geonetwork for creating records that can be published to data.gov.uk or for your own use. Installation is easy, just follow the instructions at the repository, making sure you pick the branch that matches your Geonetwork installation.

By creating a separate plugin for Gemini 2.2, it can be used alongside other profiles such as Medin, and Gemini 2.3 when it’s released. You can ensure your metadata is stored and validated against the correct profile, and that you see the correct dropdown lists and hints when you’re creating or editing records.

We’ve made sure that the validation rules align with those used on data.gov.uk, so no more tiresome tooing and froing to ensure your records are correct. We’ve also tried to make the error messages a little more friendly too, so it’s easier to understand if things do go wrong!

What’s next?


We’re currently testing the Gemini 2.2 profile against Geonetwork 3.4.x, and all signs point towards it working just fine. As soon as we’ve finished fully testing everything, we’ll update the repository and documentation to take this into account.

When Gemini 2.3 is released we will begin testing a new plugin, with the new schematron rules and any additional changes. This will include tools for translating from Gemini 2.2 to 2.3. The timescale for this is dependent on the official release of the new standard and the guidance as to what should happen to existing metadata published under Gemini 2.2.

Astun Conference 2018

In late September and October Astun hosted two regional conferences in Bristol and Leeds. In the current environment it isn’t easy to persuade people in Local and Central Government to take a day out of their schedules and travel to to a conference, so getting over 70 delegates over the two days was a strong indication of the value that Astun brings to its clients. After a brief welcome from Steven Feldman (Bristol) or Dan Ormsby (Leeds) Mike Saunt, Astun’s founder and MD, gave a keynote entitled “Much ado about Mapping” Mike talked about Astun as a passionate company, passionate about geo, passionate about open, passionate about the cloud and fanatical about support. He ran through the way Astun’s offer had evolved in the last year with new features, an improved user experience, simplified administration, more automation of cloud deployment and most importantly major investments in testing, quality enhancement and reducing technical debt. Then Mike moved on to the direction of travel for…

Making home working work!

I was chatting to a personal acquaintance recently about work and we got on to the subject of home working. The organisation she worked for was going through a period of change and they were planning on moving some of their office staff to home working on a permanent basis. She was after my views on how we manage to make that work effectively at Astun. This blog, which is very much a manager's perspective, is what I told her!

Before we get on to to the two key themes of this blog - the Technical and Cultural - a quick bit about Astun first! 1. Astun's circumstances We employ around 21 people, of which 6 or so work from an office in Epsom, and the rest work from home on a permanent basis. From my home in Bristol, I line manage 13 of those people, 3 of which are office based, the rest primarily work in the UK, as far north as Tyneside & Lancaster and as far south as Southampton. I have one member of the team who is based in Seville in Spain.
2. Technical Use of technology is k…

Wychavon District, Malvern Hills District, and Worcester City councils sponsor improvements to the Gemini metadata plugin for Geonetwork

Astun have been working with Wychavon District, Malvern Hills District and Worcester City councils on some improvements to the Gemini 2.2 Metadata Plugin for Geonetwork.

The councils approached us at one of our User Group events in 2018 for some assistance with their joint data and metadata publishing workflow. In this workflow, data is published as WMS and WFS using Geoserver. Metadata in the WMS and WFS responses are harvested by Geonetwork to create metadata records, which are then published to data.gov.uk. The goal was to create fully valid Gemini 2.2 metadata directly from Geoserver, without the need for editing the records in Geonetwork. We worked with the councils to establish that the Geoserver INSPIRE plugin and built-in metadata tools met most of that requirement, but that some elements were either incorrectly added or missing entirely when the metadata was harvested into Geonetwork.

Astun have enhanced the Gemini 2.2 metadata plugin for Geonetwork to improve it's WMS an…
