Interoperability is a characteristic of a product or system to work with other products or systems. While the term was initially defined for information technology or systems engineering services to allow for information exchange, a broader definition takes into account social, political, and organizational factors that impact system-to-system performance.
Free and open-source software (FOSS) is a term used to refer to groups of software consisting of both free software and open-source software where anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software. This is in contrast to proprietary software, where the software is under restrictive copyright licensing and the source code is usually hidden from the users.
The European Union Public Licence (EUPL) is a free software licence that was written and approved by the European Commission. The licence is available in 23 official languages of the European Union. All linguistic versions have the same validity. Its latest version, EUPL v1.2, was published in May 2017. Revised documentation for v1.2 was issued in late‑2021.
The Linux Foundation (LF) is a non-profit technology consortium that hosts and promotes the collaborative development of open-source software projects. In addition to providing a neutral home where Linux kernel development can be protected and accelerated, the LF is dedicated to building sustainable ecosystems around open-source projects to accelerate technology development and commercial adoption.
License proliferation is the phenomenon of an abundance of already existing and the continued creation of new software licenses for software and software packages in the FOSS ecosystem. License proliferation affects the whole FOSS ecosystem negatively by the burden of increasingly complex license selection, license interaction, and license compatibility considerations.
In FOSS development communities, a forge is a web-based collaborative software platform for both developing and sharing computer applications. The term forge refers to a common prefix or suffix adopted by various platforms created after the example of SourceForge. This usage of the word stems from the metalworking forge, used for shaping metal parts.
Bitnami is a library of installers or software packages for web applications and software stacks as well as virtual appliances. Bitnami is sponsored by Bitrock, a company founded in 2003 in Seville, Spain by Daniel Lopez Ridruejo and Erica Brescia. Bitnami stacks are used for installing software on Linux, Windows, Mac OS X and Solaris. VMware acquired Bitrock, along with its two largest properties, Bitnami and InstallBuilder, on May 15, 2019.
The Open Source Observatory and Repository (OSOR) is an online project launched by the European Commission under the IDABC programme, to support the distribution and re-use of software developed by or for public sector administrations across Europe, connecting EU services and Member States.
The Semantic Interoperability Community Europe (SEMIC.EU) was an eGovernment service initiated by the European Commission and managed by the Interoperable Delivery of European eGovernment Services to public Administrations, Businesses and Citizens (IDABC) Unit. As one of the 'horizontal measures' of the IDABC, it was established as a permanent implementation of the principles stipulated in the 'European Interoperability Framework' (EIF). It offered a service for the exchange of semantic interoperability solutions, with a focus on demands of eGovernment in Europe. Through the establishment of a single sharing and collaboration point, the European Union wanted to resolve the problems of semantic interoperability amongst the EU member states. The main idea behind the service was to make visible specifications that already exist, so as to increase their reuse. In this way, governmental agencies and developers benefit as they do not reinvent the wheel, they reduce development costs, and increase the interoperability of their systems.
LibreOffice is a free and open-source office productivity software suite, a project of The Document Foundation (TDF). It was forked in 2010 from OpenOffice.org, an open-sourced version of the earlier StarOffice. The LibreOffice suite consists of programs for word processing, creating and editing of spreadsheets, slideshows, diagrams and drawings, working with databases, and composing mathematical formulas. It is available in 115 languages. TDF does not provide support for LibreOffice, but enterprise-focused editions are available from companies in the ecosystem.
The Asset Description Metadata Schema (ADMS) is a common metadata vocabulary to describe standards, so-called interoperability assets, on the Web.
CloudStack is open-source Infrastructure-as-a-Service cloud computing software for creating, managing, and deploying infrastructure cloud services. It uses existing hypervisor platforms for virtualization, such as KVM, VMware vSphere, including ESXi and vCenter, XenServer/XCP and XCP-ng. In addition to its own API, CloudStack also supports the Amazon Web Services (AWS) API and the Open Cloud Computing Interface from the Open Grid Forum.
Software Package Data Exchange (SPDX) is an open standard for software bill of materials (SBOM). SPDX allows the expression of components, licenses, copyrights, security references and other metadata relating to software. Its original purpose was to improve license compliance, and has since been expanded to facilitate additional use-cases, such as supply-chain transparency and security. SPDX is authored by the community-driven SPDX Project under the auspices of the Linux Foundation.
On April 21, 2021 data.europa.eu was launched as a single access point for open data published by EU Institutions, national portals of EU Member states and non-member states, as well as international organisations of predominantly European scope. The portal consolidates datasets previously available via the EU Open Data Portal and the European Data Portal into a single meta-catalogue. The European Data Portal, launched in its beta version on November 16, 2015, was an initiative of the European Commission, and part of the Digital Single Market.
Nextcloud is a suite of client-server software for creating and using file hosting services. Nextcloud provides functionality similar to Dropbox, Office 365 or Google Drive when used with integrated office suites Collabora Online or OnlyOffice. It can be hosted in the cloud or on-premises. It is scalable, from home office software based on the low cost Raspberry Pi, all the way through to full sized data centers that support millions of users. Translations in 60 languages exist for web interface and client applications.
Marcel Kolaja is a Czech software engineer, Internet freedom and digital rights activist and a Czech Pirate Party politician who serves as a Member of the European Parliament (MEP) since the 2019 election and Quaestor of the European Parliament since 2022.

Microsoft, a technology company historically known for its opposition to the open source software paradigm, turned to embrace the approach in the 2010s. From the 1970s through 2000s under CEOs Bill Gates and Steve Ballmer, Microsoft viewed the community creation and sharing of communal code, later to be known as free and open source software, as a threat to its business, and both executives spoke negatively against it. In the 2010s, as the industry turned towards cloud, embedded, and mobile computing—technologies powered by open source advances—CEO Satya Nadella led Microsoft towards open source adoption although Microsoft's traditional Windows business continued to grow throughout this period generating revenues of 26.8 billion in the third quarter of 2018, while Microsoft's Azure cloud revenues nearly doubled.
Collabora Online is an open source online office suite built on LibreOffice Technology, enabling web-based collaborative real-time editing of word processing documents, spreadsheets, presentations, and vector graphics. Optional apps are available for desktops, laptops, tablets, smartphones and Chromebooks.
Software for COVID-19 pandemic mitigation takes many forms. It includes mobile apps for contact tracing and notifications about infection risks, vaccine passports, software for enabling – or improving the effectiveness of – lockdowns and social distancing, Web software for the creation of related information services, and research and development software. A common issue is that few apps interoperate, reducing their effectiveness.
