Market overview of general horizontal IoT platforms

Survey carried out by the Community / Working Group Standards & Platforms during our meetings 2024

During 2024 the Community / Working Group Standards & Platforms will carry out a market overview of general horizontal IoT platforms for municipal and regional operations at its meetings in close cooperation with RISE Smart City Lab. The first meeting is already on Monday, February 18th.

In 2020, the Working Group conducted a similar survey where 15 actors came and gave presentations to the Group. That market survey is documented in the Working Group’s reports from 2020 and 2021, which can be found on the IoT Sweden website and on the Collaborate web page of SEK IoT Forum. That time, the market research resulted in valuable documentation and material. The material formed the basis for, among other things, the production of procurement material was used in Region Jönköping’s two IoT platform procurements in 2020 and 2022. That procurement material is now being further developed by the “Smart Region Västra Götaland” project for their upcoming IoT procurement during spring 2024 where about 50 municipality, the VG Region and 100 companies are participating.

This year, suppliers will be invited to give a 1-hour presentation each at the working group meetings. This time we also have a clearer template for what we want to get presented. This will hopefully make it easier to compare different solutions and better understand how different platforms are positioned and what strengths and possible weaknesses they may have.

An apology in advance to all English speaking members. Some of the presentations, mainly those from Swedish vendors, will be held in Swedish. We cant force them to translate their presentation material only for these occasions. We will try to announce clearly what will be held in Swedish or English.

During the spring, the Community / Working Group will have meetings the following occasions. All at 13.00 – 15.30.

  • Monday 19 February
  • Monday 18 March
  • Monday 15 April
  • Monday 20 May
  • Monday 17 June

The community / working group’s meetings are open to all interested parties. If you are not on the mailing list for the Working Group but want to receive invitations, calendar bookings and zoom links, you can email me at Most of the meetings will be digital, but we will also try to implement one or some of the meetings as a hybrid meeting with the possibility of also meeting physically at GOTO 10 at the Internet Foundation in Stockholm.

At the first meeting, now on February 19, we will get a presentation of AssetBook (in Swedish) as well as an introduction (in English) to functions from the Open Source group Eclipse Foundation (which the Community / Working Group also heard about in August last year). Later in the spring, we will also get a presentation of some suppliers who have developed platforms based on open-source code from Eclipse.

You can read about AssetBook here: AssetBook | Samla alla smarta enheter på ett ställe

You can read about the Eclipse Foundation here: The Community for Open Collaboration and Innovation | The Eclipse Foundation

In March, the Working Group receives a visit from OS2-fællesskabet from Denmark, who present their work with OS2, an IoT platform that is being developed by several Danish municipalities in collaboration. We also get a presentation of ZettaScale, an Eclipse-based platform.

You can read about OS2 here: OS2 styrker digitaliseringen i det offentlige Danmark

You can read about ZettaScale here: ZettaScale Technology

Several additional suppliers and actors have expressed interest and will be booked during the year. We will get back with updated information as the program for each meeting becomes ready. If you are a supplier but have not registered for a presentation yet, you can contact me at The working group has developed criteria that must be met in order to come and present. This is to get a reasonable number of presentations and that these are relevant in the context. Above all, the Working Group wants to receive presentations of general platforms. For example, there is no room to look at domain-specific solutions for individual industries or applications this time.

Hopefully these sessions will be very interesting and also provide great possibilities to connect and cooperate. Welcome!

Market Dialog – Procurement of long term IoT-platform for a whole Swedish Region

Welcome to participate in the Community’s and Standards & Platforms Working Group’s first meeting for 2024. This time the meeting is an IoT Sweden Forum where the Working Group hosts the project Smart region Västra Götaland’s Market Dialogue for the procurement of a long-term county-wide horizontal IoT platform.

OBS! The meeting will be held in Swedish!

Monday 2024-01-15 13.00 – 15.00 CET


Password: 486440

The market dialogue is carried out in collaboration between IoT Sweden, RISE Smart City Lab, the project Smart region Västra Götaland and the Working Group. The participants in RISE Smart City are also invited, and IoT Sweden has extended an even wider invitation.

The dialogue will deal with selected parts of the procurement documents that VGR and the municipalities in Västra Götaland produce for the procurement of long-term IoT platforms. Among other things, pricing model and security issues. You can read more about the event on IoT Sweden’s website: 

The meeting is of interest for everyone engaged in Web of Things and Smart Cities. It´s also rather unique having over 50 Municipalities and their companies + the Västra Götaland Region and the county board invited to participate in the procurement and project.  

The procurement material will be available for vendors at the Swedish procurement portal Tendsign soon. The material is written in Swedish.  

Welcome to an interesting start of the new year!

Meeting 18 dec about Local digital twins and the metaverse

Welcome to participate in the Community’s and Standards & Platforms Working Group’s last meeting for this year, which aims at the future. We address two exciting topics that are already on the agendas of several municipalities, namely: local digital twins and metaverse that together become CitiVerse.

Monday 18 December 13.00 – 15.30 CET

Zoom link:

Password: 486440

Local digital twins are something that several municipalities have already started investing in. It is about 3D models of city districts, entire municipalities, regions, or countries that are made into digital twins by connecting them with web of things technology.

Metaverses are virtual worlds that can be “visited” through avatars, much like in a computer game world. In metaverse, it is possible to have digital meetings, events and more. Two major players who invest heavily in this are Microsoft and Meta (Facebook).


CitiVerse is when we combine these two, that is, use our local digital twins to create virtual worlds that we can then use for several different applications, for example together with Virtual Reality (VR) and Augmented Reality (AR). The EU Commission is by example already investing in CitiVerse and has had a first call where several consortia applied to contribute and take part in EU funds.

Combine web of things with digital twins

At this December meeting of the Working Group, we will focus on how we weave together the web of world with the digital twins for municipalities, regions and countries. Likewise on how we can create interoperability to feed the twins with continuously updated data from existing systems and databases.

We continuously monitor interoperability in the Community and Working Group and it is also addressed with MIM’s within the EU and ongoing interoperability projects in Sweden with Region Jönköping County.

Demonstrations of digital twins

We will talk about technology and standardization for Local Digital Twins, Metaverse and CitiVerse. There will also be presentations and demonstrations of digital twins from several Swedish initiatives. We will also hear about Destination Earth, which collects environmental data that we can use for analysis in our Local Digital Twins.

How it is discussed in the EU

The European Commission has just carried out a mapping of the standardization landscape for CitiVerse, i.e. all parts that the EU expects CitiVerse to cover. Among other things, I will talk about what has been discussed within the EU which is the basis for the EU’s investment in CitiVerse. We will also talk about the connection with the international standardization within ISO and IEC around IoT and Digital Twins as well as within W3C.

Contribute on the meeting?

Want to present something or demonstrate a Local Digital Twin or CitiVerse? Please contact me asap to see if we can fit you into the program. There are many interesting presenters on the list already so everyone needs to be brief. 

Welcome to this exciting meeting!

Update on the Nordic Chapter Smart City / Web of Things Community Group

The Nordic Chapter Smart City Community Group will now become more active.

We will use this home page for information and comments. Discussions live, in online meetings, regarding issues of interest to this group will be carried out in the Swedish forum Arbetsgruppen Standarder & Plattformar.

Arbetsgruppen Standarder & Plattformar is a think tank for IoT, Digital Twins, Smart Cities, IoT Platforms and related technology and standards. Arbetsgruppen meets once a month to present and discuss various themes that is decided jointly by the members.

Some of the themes in Arbetsgruppen will refer to ongoing work within W3C. Our intention is to actively participate and engage in relevant initiatives within W3C. That is, take part of the material produced in W3C, discuss and compare with other related material and initiatives as well as our needs and experiences. As a result we will also do our very best to provide relevant input and suggestions back to W3C and ongoing projects within W3C when appropriate.

The group also have a close relationship to TK IoT, the Swedish official standardization committee for IoT and Digital Twins, and keeps track of and discuss whats going on in other standardization organizations for IoT, Digital Twins and Smart Cities, nationally and on the international level.

Arbetsgruppen is hosted by SEK, Svensk Elstandard as an SEK IoT Forum. All presentations and material from the meetings of the group are stored online in Collaborate, provided by SEK. By becoming a member in the SEK IoT Forum (free of charge) you can gain access to that material. Please email me at to get an invite.

Arbetsgruppen is also working closely to the Swedish organisation RISE Smart City Lab where representatives of Swedish municipalities and regions gather to address concerns regarding Smart Cities and IoT.

A disclaimer: The meetings of Arbetsgruppen are currently held in Swedish. If needed, depending on the participants from this Nordic Chapter Smart City Community Group, we might change to English, if and when that is needed. Please contact me in advance if you intend to participate on a meeting in Arbetsgruppen and want us to carry out that meeting in English. 

The following meetings are currently scheduled in Arbetsgruppen:

27 November 13.00 – 15.30 CET

This meeting will focus on:

  1. An overview of the work within W3C related to the Nordic Chapter Smart City Community Group
  2. A first look (by this group) on Web of Things Architecture, Web of Things Description and Semantic Sensor Network Ontology + SOSA.
  3. Planing of a mapping and market overview of general horizontal IoT platforms. The group did this in 2020 and there is a need to do this again. Selected vendors will be invited to present their products during the meetings in Arbetsgruppen 2024.
