Participant Organizations

Madrid Positioning

Madrid, through the Digital Office of the Madrid City Council, is actively deploying IoT and 5G technologies across city services to improve interoperability and cybersecurity. Participants in this activity include Polytechnic University of Madrid, OMA, AIOTI, among others. It is aligned with initiatives like Interoperable-europe and EIRA/EGovEra.

The Madrid City Council participates in the Smart Cities SIG as:

A public administration undergoing a digital transformation process.
An organization committed to delivering the highest-quality services to its citizens.
A facilitator of open ecosystem collaboration, working with the Polytechnic University of Madrid.

Madrid's primary interest in the initiative is to bridge real municipal interoperability needs with a coherent digital twin supported by a selected set of standards, using a practical, collaborative approach to analyze needs, identify the best available solutions, and carry out testing and validation activities.

Madrid views the Smart Cities SIG as a practical environment for interoperability coordination and requirements incubation, where ecosystem participants can collaboratively:

Analyze interoperability challenges, where city experts can contribute their knowledge of how the digital twin should represent reality.
Refine reusable interoperability requirements, including the data models needed to represent the real world, maintain historical data linked to city spaces rather than devices, compare information collected by different technologies, and preserve the same semantics across all layers in an EIRA/EgovERA context.
Validate reusable approaches by deploying them in real Smart Urban Spaces, and support a catalog of devices for city-service providers, as well as a catalog of data models to help manufacturers understand the needs defined in the cities' mid- and long-term roadmap.

Madrid believes that direct collaboration with other municipalities and the wider ecosystem of incumbents, grounded in a shared and well-defined interpretation, will help everyone create long-term value.

The collaboration methodology proposed for the Smart Cities SIG may contribute to:

Specifying real needs and translating them into reusable interoperability profiles.
Defining semantic mappings from real-world operations into digital twins.
Ensuring semantic continuity by incorporating context through Smart Data Models and NGSI-LD.
Providing interoperability guidance based on collaboration at every level.
Developing reusable validation methodologies through a dual-step process: first in the laboratory, such as IoTMADLab, and then in real city settings, such as Smart Urban Spaces.

Madrid supports the initiative by providing coordination based on these principles:

Transparency.
Citizen-centricity.
Openness.
Implementation neutrality.
Practical ecosystem collaboration.

Madrid views the Smart Cities SIG as a collaborative ecosystem initiative intended to complement, not compete with, existing standards organizations, ecosystem alliances, interoperability programs, and industry initiatives.

Open Mobile Alliance (OMA) Positioning

The Open Mobile Alliance (OMA) participates in the Smart Cities SIG as:

a supporting standards organization,
an interoperability enabler,
and a facilitator of open ecosystem collaboration.

OMA’s primary interest in the initiative is to help bridge real municipality interoperability needs with reusable and standards-based interoperability approaches through practical collaboration and interoperability validation activities.

OMA views the Smart Cities SIG as a practical interoperability coordination and requirements incubation environment where ecosystem participants can collaboratively:

analyze interoperability challenges,
refine reusable interoperability requirements,
validate reusable approaches,
and identify practical interoperability gaps and opportunities.

OMA believes that direct collaboration with municipalities and ecosystem participants can help improve the practical relevance, interoperability alignment, and ecosystem applicability of reusable interoperability approaches and related standards activities.

OMA is particularly interested in understanding how reusable interoperability approaches identified through the Smart Cities SIG may contribute to:

reusable interoperability profiles,
semantic mappings,
Smart Data Models,
interoperability guidance,
reusable validation methodologies,
and interoperability testing approaches.

OMA also supports the initiative by providing lightweight program coordination intended to help maintain:

transparency,
openness,
implementation neutrality,
and practical ecosystem collaboration.

OMA views the Smart Cities SIG as a collaborative ecosystem initiative intended to complement existing standards organizations, ecosystem alliances, interoperability programs, and industry initiatives rather than compete with them.

Paradox Engineering SA Positioning

Headquartered in Switzerland, Paradox Engineering designs and develops open-standard IoT network technologies, with smart lighting as main focus. Since the beginning, the company portfolio has been having interoperability at its core, under the clear vision that truly future-proof urban digital infrastructures can only be enabled by open, interoperable, standards-based solutions.

Paradox Engineering will contribute to the Smart Cities SIG through:

Data Model Validation: Applying Paradox Engineering's extensive R&D expertise to refine and validate the initiative's data model.
Lighting & IoT Domain Expertise: Leveraging Paradox Engineering's long-standing, global experience in designing, developing and deploying standards-based smart lighting and IoT solutions.
Device Interoperability Testing: Utilizing Paradox Engineering's lighting controllers to rigorously test system performance and data model adherence.

The primary objective in this initiative is to demonstrate the tangible, real-world value that interoperability delivers to municipalities and utilities — enabling them to build resilient, future-proof, and highly adaptive smart city ecosystems, built to last throughout innovations in technology and evolutions of needs. Paradox Engineering is fully committed to serving as a trusted, experienced voice, helping cities build simple, reliable and secure IoT infrastructures.

Libelium Positioning

Libelium develops IoT sensing and software solutions for smart cities and infrastructure, connecting physical-world observations with urban data platforms, data spaces, and digital twins. Through its sensing technologies and iris360 platform, Libelium brings an end-to-end perspective on how data is generated, managed, shared, and transformed into actionable information for municipalities.

Libelium participates in the Smart Cities SIG as an IoT device manufacturer and platform provider, a contributor of practical implementation experience, and an advocate for open standards, trustworthy data, and implementation-neutral ecosystem collaboration. Libelium has also been a key promoter for a long time of OMA LwM2M with reserved objects group and a key promoter and contributor of the Smart Data Models. At the same time, the company is member of the FIWARE Foundation, with a key role in the Board of Directors.

Libelium’s primary interest in the initiative is to help municipalities achieve interoperability from physical measurement to digital representation. Its position is that successful data exchange should preserve not only a value and its format, but also what was observed, where and when the observation occurred, how it was obtained, and whether it is suitable for the intended municipal service.

Libelium proposes to contribute to the Smart Cities SIG through:

Device-to-platform semantic interoperability: Support the identification and validation of mappings between OMA LwM2M objects, relevant IPSO/uCIFI models, Smart Data Models, and NGSI-LD representations. The objective is to preserve operational meaning across device, platform, and application boundaries, while documenting mapping assumptions and gaps rather than assuming that different models are automatically equivalent. This aligns with the SIG’s approach of mapping municipal requirements to existing standards and ecosystem initiatives.
Data quality and measurement comparability: Help define reusable requirements for measurement units, calibration metadata, uncertainty, provenance, sampling and aggregation periods, completeness, freshness, and quality flags. Libelium advocates treating data quality as part of interoperability: municipalities should be able to assess whether observations from different devices and technologies are comparable and fit for a particular purpose, not merely whether their messages can be exchanged. Libelium leads a ISO 17025 compliance laboratory with the capacity to certify data quality for IoT devices, calibration and validation. Including key works about data quality representation over Smart Data Models https://link.springer.com/chapter/10.1007/978-3-032-29430-2_25
Spatial and historical continuity: Contribute approaches that distinguish the sensor, the observation, and the real-world entity or space being observed. The aim is to preserve the history of a street, building, water asset, or urban space when devices are replaced, relocated, or supplied by different manufacturers, while retaining traceability to the original observations. This directly supports the spatially anchored historical-data requirements identified in Madrid’s positioning.
Practical, multi-vendor validation: Contribute representative sensing scenarios, sample datasets, mapping examples, and reproducible test cases. Libelium supports a laboratory-to-field validation approach, assessing semantic consistency and data quality alongside technical connectivity, and documenting findings that other municipalities and suppliers can reuse. This is consistent with the validation approach described by Madrid and IoTMADLab.
Reusable data for digital twins and data spaces: Draw on the integration of IoT, data spaces, and digital twins to explore how validated observations can support multiple municipal services without losing their meaning, provenance, or usage conditions.

Libelium supports applying these contributions to the SIG’s initial public street lighting, smart water metering activities, with additional sensing domains considered according to municipality-defined priorities and the group’s agreed scope such as irrigation management, noise monitoring, environmental monitoring, air quality and parking.

Libelium believes that cities should be able to replace devices, combine suppliers, evolve platforms, and reuse data without losing operational meaning or historical continuity. It therefore supports transparency, openness, cybersecurity, data sovereignty, implementation neutrality, and validation grounded in real municipal needs.

Libelium views the Smart Cities SIG as a collaborative environment for translating operational experience into shared interoperability requirements, semantic mappings, and validation guidance. Its purpose should be to complement existing standards organizations and ecosystem initiatives, helping municipalities build trustworthy, adaptable digital infrastructures that deliver lasting value to citizens.
