Forum on the archiving of the Polish Internet


 Forum on the archiving of the Polish Internet resources 16-17 November 2021

The forum on the archiving of the Polish Internet includes two days of interesting lectures and discussions concerning this issue important e.g. from the point of view of securing this part of documentation heritage. We hope that these talks conducted in a wide range of experts, open at the same time to everyone interested in this subject, will result in developing key conclusions concerning legal, methodological and technical conditions necessary to launch the archive of Polish Internet resources, in particular those produced by the public sector.

We have invited excellent guests from Poland and abroad to participate in the Forum, including representatives of archives, libraries and institutions that have been already successfully implementing national Web archives.

The Internet resources have been archived in many countries in the world and in Europe since the mid-1990s, and the Web archival science is a dynamically developing field of knowledge. So far in Poland the Web archiving has been undertaken on a relatively small scale, and the discussion in this respect has been mainly academic. While recognising the achievements of many people and institutions, we would like to create a good atmosphere for a broader reflection and consultation, which with your participation and involvement will lead to the identification of specific solutions aimed at the construction of an optimal archive of the Polish Internet resources. Solutions which, while ensuring the quality of sets and legality of their collection, will also guarantee adequate protection of copyrights and civil rights, including respect for users’ privacy.

Lectures – combined with the session of open questions – given by our foreign partners on the first day of the Forum will provide an opportunity to learn about their positive and negative experiences related to the construction of the Web archive and the challenge of developing the rules for collecting and sharing the resources gathered in it. By gaining the best know-how and sharing it with you, we want to strengthen our future collective effectiveness in this field.

The formula of the second day of the Forum will be based on three discussion panels. The discussion within the legal panel will focus on the most important foundations and necessary legislative changes, which should ensure lawful, socially accepted collection and provision of selected Web resources. The aim of the archival methodology panel is to help develop the Polish terminology necessary for the Web archiving. Its participants will also consider how to apply the current rules for developing archive sets to re-born digital objects collected in Web archives. The technological panel will focus on necessary infrastructure solutions. During this part, we will also look for optimal ideas for software and systems enabling effective launch and maintenance of the Polish Web archive.

We warmly invite you to participate actively in the Forum. The participation in the Forum is free of charge, although it is subject to the registration. The number of participants is limited.

Daniel Gomes – Scientific Computing Unit of the Foundation for Science and Technology

Daniel Gomes started Arquivo.pt, the Portuguese Web-Archive, in 2007 and currently leads this public service. He obtained his PhD in Computer Science in 2007. His thesis focused on the design of large-scale systems for the processing of web data. He is a researcher in web archiving and web-based information systems since 2001.


Search the Past Web with Arquivo.pt

Arquivo.pt – the Portuguese Web-Archive is a research infrastructure that preserves millions of files archived from the web since the 1990s, containing information in several languages. It provides a public search service over this information. This presentation will shortly introduce the services publicly provided by Arquivo.pt and describe its functioning.


The Netherlands 

Antal Posthumus – The National Archives of the Netherlands


The National Archives of the Netherlands, as a permanent government agency and official archive for the Central Government (Ministries and their agencies), has the legal duty, laid down in the Archiefwet, to secure the future of the government record. Within this context our role isn’t one of actively forming a collection of archived websites through selecting and harvesting these ourselves. This is a key difference with other national archives, national libraries and other (inter-)national heritage institutions.

Therefore we put a fair amount of effort in advising our producers, Ministries and their agencies, in how they create and eventually will transfer this specific form of government records, archived public websites. One such example of support we’ve offered was issuing a very well received guideline on archiving websites (2018).

This guideline was also used as part of the requirements of a public European tender (2021). The objective of the tender: realizing a central harvesting platform to harvest circa 1500 public websites of the Central Government.

In 2019 we’ve started a project implementation to be able to receive this archived material. Our aim was to formulate and to implement requirements for the different aspects of the OAIS-model. In other words, we had to integrate in the existing infrastructure and workflows of our trusted digital repository (e-depot in short) processes relating to the ingestion, storage, management and preservation of and providing access to archived public websites of the Dutch Central Government.

These broad subject are central to my presentation next to more specific questions and challenges we’ve encountered such as:

Which search options will we be able to implement?

  • How to present and communicate to our users when content wasn’t harvested or was partly harvested due to (known) technical limitations of harvesting agents with handling dynamic content? Something we call non-harvestable content in our guideline.
  • Will our national metadata schema, our e-depot’s data model and the EAD as used in our collection management system suffice to provide adequate administrative, descriptive and technical metadata for archived websites? Or do we need to combine our national schema with another international schema?
  • Will the off the shelf viewer, Open Wayback, as it is installed in our Preservica solution, do the trick? Do we need to install a separate viewer in our infrastructure?
  • What’s WARC-validation and which tools to validate with?

European Union

Silvia Sevilla – Publications Office of the EU

Silvia SEVILLA is coordinator of the web preservation service at the Publications Office of the European Union (OP), an inter-institutional body based in Luxembourg that centralises all publications of the European institutions. Silvia has a degree in law and postgraduate studies in business administration and publishing. She joined the Publications Office in 2005 and since then has held various positions in publishing and archiving services. She has been in charge of the web archive since the creation of the service that manages it within the Publications Office in 2018.


The European Union (EU) is a political and economic union of 27 Member States. On behalf of the EU institutions, the Publications Office of the European Union (OP) creates an EU web archive. It aims to archive web content concerning the EU project to preserve it for the long term and to keep it accessible for the public. The archive covers the various websites of the EU institutions, bodies and agencies. The majority of these are hosted on europa.eu, the domain that spans the entire institutional framework of EU powers and regulatory bodies.

The websites included in the seed list are archived regularly, at least four times per year. Captures can be scheduled as often as appropriate. It is also possible to create ‘ad hoc’ archives, if a website owner makes a justified request. The most common reason for requesting an exceptional file of a page or document is that the content is going to be put offline or changed significantly.

Our web archive is created in partnership with Archive-it (Internet Archive). This platform offers automatic tools for managing seeds, scoping and cataloguing, with the possibility of ingesting metadata at the seed or collection level. It supports automatic crawling, that can be scheduled, full text search and hosting. There is a quality control system and it is possible to download WARC files.

The presentation will outline the main characteristics, content and scope of the EU web archive as well as the archiving process and the tool used. It will cover some of the challenges and strategies developed to respond to them.

Mar Pérez Morillo – National Library of Spain

Mar Pérez Morillo is PhD in Latin Language and Literature. She started working at the National Library of Spain (BNE) in 2004. Since then, she’s been in charge of the institutional website, the Library social media, the Web Archiving and the Non-Print Legal Deposit. Nowadays, she is the Director of Digital Processes and Services at the Library being her main tasks:

  • the coordination of the re-use projects,
  • the online portals of the Library,
  • the online library catalogue,
  • the Digital Library,
  • the Non-Print Legal Deposit (including the Web Archive) and
  • the long-term digital preservation program.


The non-print legal deposit and the preservation of born-digital heritage

The National Library of Spain started crawling the Spanish Web on 2009, with the help of Internet Archive. This was afforded as one of the main Library duties: preserving the documentary heritage, as the publications were increasingly moving from the physical devices to online. Since then a new Legal Deposit Law was enacted (in 2011) to consider the online publications in scope of the Legal Deposit. As Spain has a regional structure with autonomous governments, the autonomous regions have competencies on legal deposit. So the non-print legal deposit in Spain, including the Web Archive, is a collaborative project where the regional libraries select and manage their own online collection in cooperation with the National Library of Spain. So far, the size of information archived is 1 Pb and the collection consists on a combination of annual crawls of the .es domain and selective crawls on different topics that require a specific management.

Archiving the Croatian Web

Web resources differ from other types of resources that libraries are curating in many ways: frequent change of URLs, content and size, short and unpredictable life cycle, etc. In Croatia, the task to save these types of resources for future generations belongs to the National and University Library in Zagreb. The Library in cooperation with the University Computing Centre University of Zagreb (Srce) in 2004 created a system for archiving web content – Croatian Web Archive. The presentation will provide an overview of the seventeen years of experience in archiving the Croatian web with the emphasis on the existing workflows
