Last updated on May 10th, 2022 at 05:27 pm

Does your website present “Error 404 – Page not found” messages to your users?

Arquivo.pt offers a solution for this problem through arquivo404.

Just insert a single line of code in the page that generates the 404 error message on your website.

How Arquivo404 works

example-fccn-arquivo404_

When a page is no longer on a website, Arquivo404 checks if a preserved version exists.

When a user tries to access a page that is no longer available on a website, arquivo404 automatically checks if there is a version of that page preserved in Arquivo.pt.

If the page exists in Arquivo.pt, a link is presented so that the user may visit this version. If it does not exist, the normal error page is displayed.

See Arquivo404 at work in this example of an error page that presents a link automatically generated by arquivo404.

How to install file404 on your website?

The simplest implementation of file404 is to insert the following line of Javascript code on the 404 error page:

<script type="text/javascript" src="https://arquivo.pt/arquivo404.js" async defer onload="ARQUIVO_NOT_FOUND_404.call();"></script>

The code in file404 can easily be adapted. You can for example create a customised error message.

How to preserve Web references from Wikipedia?

thumbnail-wikimedia

Last updated on May 19th, 2022 at 07:05 pm

Wikimedia Portugal has started a collaboration with Arquivo.pt that aims at raising the community’s attention to the preservation of contents published on Wikipedia.

Eighty percent of the pages published on the Web disappear or are changed, just one year after their publication. At the same time, the information in Wikipedia is based on information mostly published on the Web. The disappearance of reference information undermines the reliability of Wikipedia articles.

Webinar cycle “Cultural Heritage on the Web: how to preserve references in Wikipedia?”

The cycle of Webinars, promoted by Wikimedia Portugal, includes educational content that enriches the training of information and communication professionals but also the digital literacy of any citizen.

Arquivo.pt and the preservation of digital memory (1st Webinar)

Gonçalo Themudo, President of Wikimedia Portugal, introduced the 1st webinar of the cycle entitled Cultural heritage on the Web: how to preserve references in Wikipedia?. He stressed the importance of preserving the references (URLs) used by authors when publishing articles in Wikipedia. Daniel Gomes, Manager of Arquivo.pt, showed how Arquivo.pt preserves Web contents and how the community of Wikipedia authors can contribute to the effective preservation of those contents.

Portuguese municipal elections 2021 preserved by Arquivo.pt

thumbnail_eleicoes_autarquicas

Thousands of pages about the elections to preserve before they disappear

On 26 September 2021 the local elections were held in Portugal, an event marked by the Covid-19 pandemic. The communication of the candidates was mainly based on the media and publications through the Web.

Electoral websites are of manifest historical importance. However, they are difficult to identify because they appear and disappear quickly. In the case of municipal elections, the number of candidates and the variety of channels used makes the task even more challenging.

Arquivo.pt, as in previous elections, launched a special collection to preserve contents concerning the municipal elections.

How was the electoral content published on the Web identified

The first step was the manual identification of election-related content by municipality and parish. For this purpose help was requested from people and organisations with the following initiatives:

  • collaborative list “Municipal Elections 2021: we need your help!
  • request for collaboration from the archive services of the 308 municipalities in the identification of electoral sites and candidates of the respective municipality;
  • request to the Parties to send the names of their lead candidates.

The Eyedata – Social Data Lab site was used, which made the names of candidates from all over the country available on the Web.  The Wikipedia page Eleições autárquicas portuguesas de 2021 was also used as a source of information.

The list with names of candidates by county, party or coalition was used to create automatic searches in Bing that identified the most relevant electoral contents.

For instance, by combining the term “autárquicas 2021” with the name of a candidate and the respective municipality, one obtains results related to that candidate, such as news, initiatives of his/her campaign or the official page of his/her electoral campaign.

This methodology was applied in the Presidential Elections 2021 and in the Europeia Elections 2019. The technical report A transnational crawl of the European Parliamentary Elections 2019 details the applied methodology.

Content collection and availability in Arquivo.pt

Between 22nd August and 8th October 2021, the Arquivo.pt gathered, in an exhaustive manner, pages related to the Local Government Elections 2021.

The resulting collection called Municipal Elections 2021″ (EAWP39) gathers 31 million files that total 2.7 TeraBytes of information and will be available one year later.

Researchers who want to make a study on the 2021 Local Elections and need early access to the collected contents can contact Arquivo.pt.

Thumbnail-projeto-para-sempre

Last updated on February 8th, 2022 at 10:57 am

The exhibition Memória de festivais e eventos de arte proposes a look at the Portuguese art scene present on the Web and includes a chronology of these events.

cartao-expo-memoria-festivais-e-eventos-de-arte

Online exhibition – arteparasempre.wordpress.com

The project’s second online product will be a directory of references of artists, galleries and projects in the area of contemporary Portuguese art to be made available during 2022, at the Gulbenkian Art Library webpage.

Cycle of Webinars “Art forever on the web”

A cycle of Webinars entitled “Art forever on the web” was held, between April and July 2021, oriented to artists, curators, gallerists and event producers, among others.

The average number of participants was 58 per session, who evaluated their satisfaction, on a scale from 1 to 5, with an average score of 4.6. The three sessions aimed at disseminating knowledge about digital preservation of information on the web and requirements for publishing preservable information.

Identification of artists, galleries and projects

The first step was to identify relevant artists, galleries and projects in the contemporary Portuguese art scene. We started from an initial set of 63 agents (artists, galleries and projects), to which 573 artists belonging to the Modern Collection of the Calouste Gulbenkian Foundation and the BAA – FCG Collection of Artist Books and Independent Publishing were added.

Throughout these months, 636 elements were thus identified (social networks and websites active in 2020), which were subsequently analysed.

The conclusions of the analysis carried out within the project were presented in the last webinar, held on July 1, 2021 :

Special feature on art websites and blogs

In April 2021, Arquivo.pt made a special collection based on the initial identification of artists, galleries and projects and obtained 2.8 terabytes of preserved information.

New contents about art websites were recorded, using tools that allow higher quality collections, such as Brozzler and Webrecorder.

A collaborative project of digital curation

“PARA SEMPRE” (forever) is a digital curatorial project applied to the information made available on the web by the several agents of the contemporary Portuguese art scene (artists, galleries and hybrid sites).

Its main purpose is to contribute to the preservation/reuse of past and future pages, to ensure the preservation of the digital memory of current Portuguese art available at Arquivo.pt, and to promote knowledge on this theme by presenting it in a systematized and structured way.

Its creation results from the encounter of the missions of two organizations: one that aims to ensure the preservation of the Portuguese web, Arquivo.pt, and another that assumes itself as an agent in the development of knowledge about contemporary Portuguese art, the Calouste Gulbenkian Foundation Art Library. This is part of the ROSSIO (Research Infrastructure in the Social Sciences, Arts and Humanities).

December 9 – Publish on the Web: best practices  by Arquivo.pt

Pedro Gomes, the engineer responsible for the Arquivo.pt crawls, addressed the issue of publishing preservable web contents. How many contents are in formats that make their future access difficult or impossible? These situations were illustrated with practical cases and recommendations on how to avoid them. Therefore, it all boils down to publishing well in order to preserve well.

Create automatic narratives about any topic!

thumbnail-narrative-q2

Arquivo.pt provides a new function that allows you to automatically create temporal narratives on any topic.

The “Narrative” functionality, integrated into Arquivo.pt in September 2021, is the result of the collaboration between “Conta-me Histórias”, winner of the Arquivo.pt Award 2018, and Arquivo.pt.

The Conta-me Histórias” (Tell me Stories) project was developed by researchers from the Laboratory of Artificial Intelligence and Decision Support (LIAAD – INESCTEC )  and affiliated to the institutions Instituto Politécnico de Tomar – Center for Research in Smart Cities (CI2) ; University of Porto and University of Innsbruck .

How it works?

When a user enters a set of words about a topic in the Arquivo.pt search box and clicks on the “Narrative” button, the user is directed to the “Conta-me Histórias” service, which automatically analyzes the news from 25 websites archived by Arquivo.pt over time and presents a chronology of news related to the topic.

For example, if we search for “Just Bieber” and click on the “Narrative” button (Figure 1), we will be directed to the “Conta-me Histórias” , where we will automatically obtain a narrative of archived news (Figure 2).

example-narrative-arquivopt

Figure 1: Search results for pages about “Justin Bieber”.

example-tell-me-stories-arquivopt

Figure 2: Narrative of news about “Justin Bieber” from Portuguese news sites preserved by Arquivo.pt generated by the “Conta-me Histórias” service.

Create your narrative now!

“Conta-me Histórias” researches, analyzes and aggregates thousands of results to generate each narrative about a topic. It is recommended to choose descriptive words about well-defined themes, personalities or events to obtain good narratives.

Creating a narrative is useful for researchers, journalists or citizens who want to quickly get an overview of the evolution of a topic along time, thus saving them a lot of time and effort.

Go to Arquivo.pt and try to create a narrative about a theme of your choice.

Tell us about your experience so we can improve the service!

Meet the new book The Past Web Exploring Web Archives arquivo.pt/book

 

The deadline to freely download the book was extended to 20th March!

 

Since 2006, a book has not been published that reflects the state-of-the-art in the area of ​​web preservation and the research that has been conducted on web archives.

The main goal of the new book The Past Web: Exploring Web Archives was to create a new, up-to-date resource to educate more people in the field of web preservation and to make web archives known to researchers and academics.

As such, the book is primarily aimed at the academic and scientific communities, and presents the most innovative methods for exploring information from the past preserved by web archives.

Daniel Gomes, manager of Arquivo.pt led the book’s editorial team, which also included the field specialists Elena DemidovaJane Winters and Thomas Risse. In total, the book resulted from the contributions of 40 authors from around the world who are experts in web archiving.

The book is divided into 6 parts where we find various resources for exploring pages archived from the Internet since the 1990s.

We can also learn how to preserve our collective memory in the Digital Era, which strategies to use when selecting online content, and what impact web archives have on preserving historical information.

The book aims to support professors in their mission to transmit innovative and adequate knowledge for the digital literacy required to train professionals for the 21st century.

The manager of Arquivo.pt alerts to the need of including web archives in teaching plans and emphasizes that this knowledge brings a great competitive advantage especially for students of  Humanities and Social Sciences.

An innovative detail of this book is that all its cited links have been preserved by Arquivo.pt in order to ensure that the references remain valid over time.

The book is available for free to be downloaded from Portuguese higher education institutions (b-On member entities) until March 6th 2022!

If you do not belong to a Portuguese higher education institution, you can download a pre-print version of the book (Green Open Access).
