Background

FIWARE brings a curated framework of open source software platform components which can be assembled together and with other third-party components to build platforms that support the development of Smart Solutions faster, easier and cheaper. The main and only mandatory component of any โ€œPowered by FIWAREโ€ platform or solution is a FIWARE Context Broker Generic Enabler, supplying a cornerstone function required in any smart solution: the need to manage context information, enabling to perform updates and bring access to context.

FIWARE NGSI is the API exported by a FIWARE Context Broker, used for the integration of platform components within a "Powered by FIWARE" platform and by applications to update or consume context information. FIWARE NGSI API specifications have evolved over time, initially matching NGSI-v2 specifications, now aligning with the ETSI NGSI-LD standard. The FIWARE Community plays an active role in the evolution of ETSI NGSI-LD specifications which were based on NGSI-v2 and commits to deliver compatible open source implementations of the specs.

Building around the FIWARE Context Broker, a rich suite of complementary open-source FIWARE Generic Enablers are available, dealing with the following:

FIWARE is not about take it all or nothing. You are not forced to use these complementary FIWARE Generic Enablers but are free to use other third platform components as well to design the hybrid platform of your choice. As long as it uses the FIWARE Context Broker technology to manage context information, your platform can be labeled as โ€œPowered by FIWAREโ€ and solutions build on top as well. Listings of many FIWARE Ready devices and commercial โ€œPowered by FIWAREโ€ solutions can be found on the FIWARE Marketplace.

To be adopted as a Generic Enabler within FIWARE, each open source component must fulfil a number of contribution requirements. The technical direction of FIWARE is governed by the FIWARE Technical Steering Committee (TSC). Developers can also subscribe to the FIWARE TSC mailing list, join the FIWARE TSC regular confcalls as observer and follow the progress of the discussions through the FIWARE TSC meeting minutes.

Deployment Tools

FIWARE Catalogue

Most FIWARE components are available as Docker Images, direct links can be found within the descriptions of each generic enabler. A docker-compose.yml may also be available within the GitHub repository, but these should only be used in development environments. For fully scalable production-ready instances of FIWARE Generic Enablers please refer to the repository holding the FIWARE Helm Chart recipes or find FIWARE Helm Chart receipes directly on ArtifactoryHub

Data Spaces

FIWARE brings the essential building blocks helping to create Data Spaces enabling access and share of data in an effective and trustworthy manner. The open source nature of FIWARE technologies foster creation of these data spaces as federated infrastructures where multiple providers can be involved and not just a few players. FIWARE is bringing today mature technologies, compatible with IDS and CEF Building Blocks, that may accelerate the delivery of data spaces to the market and the materialization of initiatives like GAIA-X in Europe.

The concrete selection of FIWARE components proposed as building blocks for the creation of Data Spaces can be found on dedicated pages linked to FIWARE for Data Spaces.

Management of FIWARE Releases

The individual components within the FIWARE catalogue are free to make semantic versioned releases at any time. Additionally, a labelling of the whole FIWARE catalogue takes place at regular intervals where all components are collected together and a FIWARE label added according to a set of well-defined rules. The FIWARE catalogue release schedule follows a strict timetable. Versions of components with the same FIWARE release label should be completely interoperable and work nicely with each other.

๐ŸŽฏ ย  Roadmap ๐Ÿš€ ย  Release Notes

As well as source-code repositories and binaries, relevant components are available as container registry images and Helm-chart recipes for Kubernetes. Smart Data Models for NGSI-v2 and NGSI-LD help to define harmonised representation formats and semantics that will be used by applications both to consume and to publish data.

Testing

FIWARE is ready to work in industrial environments. A continuous quality assurance process is running to warranty the level of reliability in FIWARE Generic Enablers. Following the energy labelling system applied by European Union for devices, each Generic Enabler is assigned with an overall label in the Catalogue (A+++, A++, A+, A, B, C) according to the obtained results in testing different aspects.

A testing method has been defined to conduct documentation verification, functional tests (verification of Generic Enablers specifications and APIs testing) and non-functional tests such as performance, stability and scalability. The tests are executed for every new version of the Generic Enablers, providing valuable insights to the Generic Enabler owners for improving the next Generic Enabler release.

All the tests can be conducted by anyone since the files for defining and running the tests have been published in an open source repository.

Full details of the test results can be found on the FIWARE site - a summary of the test results is presented for each enabler within the submodules below.

Mature Generic Enablers have been thoroughly tested and have already demonstrated useful role accepted within the FIWARE framework. Incubated Generic enablers (annotated with ๐ŸŒฑ) have also been tested, but are still in the process of maturing to full acceptance with the FIWARE system. Recent applicants to FIWARE (annotated with ๐Ÿ†•) are new to FIWARE and will undergo testing in the forthcoming release.

Willing to contribute your technology to FIWARE?

The application process for joining the FIWARE Initiative is described in the links below. To be adopted as a Generic Enabler within FIWARE, each open source component must fulfill a number of contribution requirements, follow common Open Source Best Practice and sign-up to the harmonized FIWARE Entity Contributor License Agreement. The technical direction of FIWARE is governed by the FIWARE Technical Steering Committee (TSC).

You can contribute to FIWARE technically by different means: contributing code for a given FIWARE component, helping to develop tutorials/training material which are made freely available to developers, supporting QA activities or supporting the operations of the FIWARE Lab.

Further information on the use of the GPL or AGPL open source license

Some FIWARE Components are distributed under GPL or AGPL open source licenses โ€ฆ Is it safe for me to use?

Absolutely. Issues with GPL (or AGPL) licenses are mostly related with the fact that different people assign different interpretations on the meaning of the term โ€œderivate workโ€ used in these licenses. Due to this, some people understand that there is a risk in just using software under GPL or AGPL licenses (even without modifying it).

In order to avoid any issue, FIWARE Generic Enabler owners who have decided to release their software using a GPL or AGPL license are required to make a public statement that states:

Please note that software derived as a result of modifying the source code of this software in order to fix a bug or incorporate enhancements is considered a derivative work of the product. Software that merely uses or aggregates (i.e. links to) an otherwise unmodified version of existing software is not considered a derivative work.

The public statement above is aimed at giving users confidence they can use FIWARE components even if they have been licensed under a copyleft license without this requiring that their applications have to be released as open source. The FIWARE Foundation has sought legal advice regarding this statement and has been told that incorporation of this paragraph is valid for this purpose as per the report produced by Across Legal/ID law partners (see summary report).

This means that there is absolute no risk that you are forced to release the software that you may have developed using FIWARE Generic Enablers under a GPL, AGPL or any other open source license.
