Ivan Marić, CEO of Srce from 1st April 2021, Ivan Marić, deputy director – CTO until 31st March 2021
We are in a year in which the University Computing centre SRCE celebrates 50 years of its activity. The foundation of SRCE was a response to the needs of the academic community, but also of the entire Croatian society, to start a more systematic and comprehensive application of new information and communication technologies, thus modernizing and transforming education and research processes. Therefore SRCE has been, for fifty years now, in the very heart of what we today call the digital transformation of science and higher education.
With its activities, covering all layers of e-infrastructure, from data centres, through network, computer and storage resources, then the middleware, and up to information services and advanced user support, SRCE is a unique institution not only in the science and higher education systems, and not only in Croatia. This uniqueness has opened and still opens many opportunities both for SRCE and for science and higher education systems. Today, SRCE is a synonym for the national e-infrastructure of the science and higher education system and an indispensable factor in the digital transformation of science and education.
In the early 1990s, by building the national academic network on Internet protocol, SRCE played a key role in the birth of Internet in the Republic of Croatia. Today, hosting the Croatian national centre for the exchange of Internet traffic - CIX, we can say that we are the very heart of the Croatian Internet. In developing new strategic projects, we will be guided by the pioneering role of SRCE in the innovative introduction of new technologies and services, ensuring that the academic and research community are always one step ahead of other parts of society, for the benefit of the society as a whole.
SRCE was established fifty years ago with the task of providing the necessary mechanism to address the upcoming digital needs of the academic and research community. In order to carry out this task equally successfully in the future, we pay special attention to building bridges to key stakeholders in the science and higher education system in order to engage the community in building, managing and maintaining common components of e-infrastructure and digital services. Also, with our membership and participation in the work of international bodies, associations and projects, we build bridges connecting the Croatian national e-infrastructure with the pan-European one, with the aim of integrating the Croatian Research Area into the European Research Area (ERA) and European Higher Education Area (EHEA).
Thank you for joining us and for supporting us on this challenging and exciting journey that has been going on for fifty years now.
Established under the auspices of the University of Zagreb, at that time the only university in Croatia, based on the decision signed on 29 April 1971 by the rector Ivan Supek, SRCE has made and enabled many breakthroughs in the application of the latest technologies in science, education and also in the whole Croatian society. This is why we can really say that the history of SRCE is also an important part of the history of Croatian informatics. We present you a part of that history through a series of historical notes on this anniversary website.
Today, SRCE is building a modern e-infrastructure and a multitude of digital services for the needs of modern education and internationally relevant and recognizable research. Generally speaking, the activities of SRCE are focused on various aspects of effective data, information and knowledge management, which represent the fundamental values of every society, and especially the science and higher education systems. Apart from building the e-infrastructure and systems that enable data and information curation throughout their life cycle, SRCE is recognized for its support to all users and education and training programs, essential for technologies to come to full expression and realize their full potential.
In doing so, and especially in the last 20 years, SRCE has been paying special attention to connecting Croatian e-infrastructure with the European and global one, thus creating preconditions for connecting the Croatian educational and research space with the European one, enabling the flow of information and ideas, opening up space for cooperation and exchange of experiences and best practices, which are all characteristics of open education and open science, that SRCE today promotes, practices and enables through its services. As synonyms for a modern and high quality education available to all, and collaborative, transparent and fast-performing research, open education and open science today are certainly the guiding principles of SRCE on the way to new breakthroughs in the application of new technologies and the development of advanced digital services.
When I was first employed at the University of Zagreb, I had the opportunity to work with colleagues who had worked at SRCE from its very inception. At that time, SRCE had existed for 20 years. These colleagues' memories and their descriptions of SRCE's beginnings have been a great inspiration to me. Later, when I got a job at SRCE, it felt like I was coming to an environment I was already well acquainted with.
In its 50 years of existence, many things were changing and have changed at SRCE. Computer paradigms, technology, the social environment and the impact of informatics on society, standards and user expectations have changed. At the same time, the structure of its users remained stable. The primary users of SRCE always have been students, university professors and scientists. At certain periods, users from other environments would join them.
For me, the greatest achievement of SRCE is that, regardless of the circumstances and the severity of the challenges, it has always managed to offer a reliable IT support to its users, focusing not only on technical aspects, but also on consulting services. In addition, SRCE also represents an important educational space.
Today, SRCE is facing a new big challenge – the current challenge of the digital transformation. And this is a twofold challenge for SRCE. On the one hand, SRCE must provide its users with the tools required to support the digital transformation in their environments and the help necessary to make use of them. On the other hand, SRCE is also facing its own digital transformation. This may be the biggest, but also the most exciting challenge so far.
It fills me with great pride to be in the very centre of the Croatian Internet, and not only to be there, but to literally create it. In 1991, the NSFNET network connected research and educational institutions in the USA (with some exceptions), but decided to open wide access to all ISPs that supported the TCP/IP protocol. Croatia was connected to DECnet network through SRCE, and there was a global war between OSI and “Internet” standards (TCP/IP), and in 1992 SRCE decided to go with Internet. This was not a move without risks and complications because it brought many adjustments to the existing network equipment, including the transition to completely new operating systems - from VMS to Unix. "The rest is history ..." For many years, there have been no ISPs in Croatia, so SRCE is the real centre of the Croatian Internet.
Today, SRCE creates and provides a number of fantastic information and data services tailor made for the academic and research community, as well as unique national systems, such as the ISP Internet Traffic Exchange Center in Croatia or advanced computing resources. The heart of these systems of SRCE at the technical level is the computer-network infrastructure (CNI), and its very essence are people, experts planning, developing, tirelessly looking after it and cherishing it. To someone with less love for technology it may seem boring to maintain routers, servers, storage ... but ensuring the balance between robots (IT equipment) and their needs on the one hand, colleagues who manage services and through them users and their requirements on the other hand, and finally the people from CNI who operate technical systems, I consider my favourite success in the past 28 years living in the very heart of SRCE.
In the future, SRCE has to continue to meet the needs of the research community that cannot be adequately met in the market, but also to be a pioneer in the implementation of new technologies, first for researchers, and then they will be transferred to other parts of the society – just like the Internet in the late 1990s. Maybe in ten years we will write that SRCE has introduced the first system for artificial intelligence in Croatia in 2021....
Education plays a key role in the society, because only educated citizens can contribute to the development of a particular society and the realization of social and economic change. Education is essential for the development of citizens, starting from school to employment and throughout life, bringing them closer to everyday life and the world of work, and enabling them for modern life and for active participation in the society. Although SRCE has been operating for 50 years as the central infrastructure institution of the entire science and higher education system, the part related to education and training of users for the use of new technologies has been present since the very beginning of its operation.
Since early 1972, SRCE has been continuously preparing, organizing and conducting educational programs, courses and workshops in the field of information and communication technology and related fields, as well as in the field of statistics. Today information and communication technologies are an integral part of everyday life, they have a significant impact on learning, teaching and research, they have become an important factor in employment, and they are essential in many aspects of society. Therefore, in SRCE, we strive to provide citizens, and in particular teachers and students and IT specialists, the necessary training and education by choosing the appropriate courses. In addition to classroom courses, a large number of the self paced online courses are available, and since recently we have started with online courses with the guidance of lecturers. Within SRCE there is also the E-Learning Centre, providing support to higher education institutions, teachers and students at the national level in the implementation of e-learning in the educational process. Actively acting and considering which educational activities to offer to its stakeholders and how to proceed, in order for them to acquire the necessary knowledge and skills, and ensuring that information and communication technologies can be used easily and efficiently, SRCE contributes to the development of the society, and wholeheartedly shares the acquired knowledge and experience with the community, contributing to the digital transformation of the science and higher education system.
Since its founding in the early 1970s, SRCE has established itself as a significant factor in the design, construction and maintenance of various information and application systems for the needs of the national research and educational community, as well as the society as a whole, collaborating with the research and education community on the one hand, and with relevant ministries and institutions of special importance for the Republic of Croatia on the other hand.
From foundation until today we are continuously present and achieving results in the field of application of new information and communication technologies. Every positive shift in the application of ICT in the Croatian academic and research community, especially at the University of Zagreb, is connected with SRCE as a collaborating or leading institution. These shifts were often significant for the entire Croatian society - let's just remember the program support for major sporting events or the introduction of Internet technologies. Thanks to SRCE, members of the academic and research community were the first to have the opportunity to use Internet services, and they were the first to receive electronic identities.
SRCE is characterized by continuous monitoring of the development and examining possible applications of new technologies on the one hand, and taking care of the establishment and maintenance, i.e. coordination of information, computer and communication services for the needs of science and higher education on the other hand.
It has been and remains challenging to take care of a range of existing services and, in addition, to consider how to use new technologies and solutions, introduce new services and transform the existing ones.
In its fifty years of work, SRCE has always relied on cooperation with its user community, the environment in which it operates, and on international projects.
I am convinced, however, that it has achieved its results and is still achieving them today, primarily thanks to its past and present human resources. I hope that this, in my opinion, core value of SRCE, will not only be preserved but also promoted.
The business of SRCE is focused on quality and transparent performance of tasks in the field of finance, legal affairs and procurement, human resources, administrative affairs and maintenance of the devices and the office building of SRCE.
We pay special attention to the continuous development and management of human resources, which are the core value of SRCE. We aim to develop standards of excellence in human resources management through monitoring key HR indicators, and to become more accessible and visible to potential candidates in the labour market. It is extremely important to us that the employees of SRCE are satisfied with the management, internal communication, work tasks and working conditions, and we will pay special attention to the development of these segments in the future.
The team for devices and office building maintenance, through continuous work and commitment, provides a continuous, reliable and quality support to the existing e-infrastructure of SRCE.
In the upcoming period business steps will be focused on improving and developing a modern and high quality management system that will, along with new information and communication technologies, provide help for the governing bodies of SRCE in a more efficient decision-making.
In its work so far, SRCE has been a leader in the application of new information and communication technologies, and has enabled many breakthroughs in the application of the latest technologies in science, education and the entire Croatian society. I believe that in the upcoming period, with our high quality, excellent, motivated and internationally acknowledged employees, we will be able to continue our path of developing modern information and communication technologies.
The E-learning Centre was established in 2007 as the unit in SRCE based on the outcomes of the international Tempus project EQIBELT with aim to enhance and support implementation of e-learning at the University of Zagreb, The E-learning Centre. Some of the basic objectives of the E-learning centre at that moment were:
Over the years, the E-learning Centre justified its existence by maintaining and providing accessible, reliable and user-friendly e-learning platform Merlin and high quality support to teachers and students. This resulted in the increased number of users and expansion to other universities and higher education institutions in Croatia. Today the E-learning Centre team is the central unit providing support to higher education in Croatia in systematic implementation and use of e-learning in educational process on the national level. With more than 24.000 e-courses for the academic year 2020/2021, over 9.500 teachers and with more than 85.000 students the Merlin is the biggest and the most modern e-learning platform for higher education in Croatia. The support to users is one of the priorities of the E-learning Centre at SRCE and is carefully planned aiming to recognize specific needs of our potential and existing users. Besides the possibility to contact helpdesk, users can find manuals and guidelines, animations, frequently asked questionsand number of training courses (face to face and online) related to the use of Merlin and other tools the E-learning Centre provides: on the topic of course design, learning outcomes, multimedia and so on. The E-learning Centre is also active on the international level, collaborating with colleagues and teams from European universities, participating in the international projects, attending conferences and sharing its experience and expertise.

Since its foundation SRCE has been enabling the acquisition of new knowledge and skills on the application of technology to all interested users at higher education institutions and research institutes in Croatia. In our 49 year long tradition the educational offer has been adapting to the development of new technologies and the users’ needs. The rich history of the development of SRCE’s educational services can be viewed on the web page Crtice iz prošlosti (in Croatian). Here we highlight the services that today form the core of SRCE’s educational offer.
The basic educational programmes known as Tečajevi Srca include a vast range of courses that provide quality and diverse education in the areas of computer literacy, use of computer programs, the Internet and more. The list of basic educational programmes consists of more than 50 courses, both face-to-face and online. The participants in this educational programmes are mostly students, teachers and citizens.
Educational programmes for IT professionals consist of courses, seminars and workshops in the field of information and communication technology and infrastructure intended primarily for system administrators at higher education institutions and research institutes in Croatia. Our educational programme edu4IT, completely developed at SRCE, is part of a European Commission’s initiative “Shaping Europe’s digital future”. Our other popular programme is Linux academy. In order to inform our community about relevant news concerning system administration and software development we also maintain https://sistemac.srce.hr/ portal.
At our testing centre anyone interested in verifying acquired knowledge in the field of ICT can take exams and gain internationally recognized certifications available through Pearson VUE organization. The long-term quality of our work is regularly confirmed with exceptional results of external quality controls. Since 2003, when testing centres were established, more than 12 000 exams have been taken at SRCE.
We are also conducting activities related to data analysis in education and science. Those activities are divided in two main areas. The first area is the planning and organizing of educational programmes in order to train students to independently perform statistical and graphical data analysis with statistical software like R. The second area is preparing analysis and reporting based on available data in science and higher education, including academic analytics and learning analytics.
Authentication and authorisation infrastructure of science and higher education in the Republic of Croatia - AAI@EduHr - is a middleware infrastructure whose basic task is to enable secure, reliable and efficient electronic identities management and their easy use for accessing network and networked resources.
AAI@EduHr has been proven as a key system that enables owners of electronic identities (scientists, teachers, students and pupils) secure and easy work in a virtual environment, which has been especially important in conditions caused by COVID-19 pandemic. At the end of 2020, the AAI@EduHr system encompassed 241 home organisations – identity providers and the central directory of all primary and secondary schools in the Republic of Croatia with a total of more than 920,000 electronic identities that their owners could use to access more than 860 different services. In addition, more than 4100 services from about 70 federations around the world are available through eduGAIN.
In 2021, AAI@EduHr celebrates 15 years since its launch: the system was launched on 1 March 2006. That year, AAI@EduHr was one of the first electronic identity federations in the global academic and educational community, with everything that makes this federation a circle of trust: organisational, informational and technical/technological rules (defined through the AAI@EduHr Policy and accompanying documents).
Its huge and lasting work, which makes the AAI@EduHr a rare case in the world, is a specific support to home organisations, and partly to service providers, through the maintenance of software packages allowing the installation of software to support certain functionalities on the selected platform (Linux Debian) (e.g. home organisation’s LDAP directory).
Srce is actively involved in international projects (e.g. MyAcademicID or as a CARNET partner in the GÉANT project series for more than 10 years) and working groups (especially within REFEDS community) dealing with issues related to middleware and authentication and authorisation systems.
Srce is recognized and accepted by international partners as the operator of national authentication and authorisation infrastructure and a reliable partner in building global middleware systems.
