Fénix: the new release of Arquivo.pt!

We are pleased to announce that we launched a new release of Arquivo.pt – the Portuguese Web Archive, after two years of suspension in the development of the service.

The name given to this release was opportunely Fénix (Phoenix). 20 cases that originated the following improvements were resolved:

Informative site (sobre.arquivo.pt):

  • Review and update of all content (152 pages in Portuguese and English);
  • Reorganization of the Information Architecture;
  • Fix functional and usability errors;
  • Incoherence of graphical style.

Search and access (www.arquivo.pt):

  • Interoperability improvements (e.g. URLs following the Wayback syntax, OpenSearch API fixes);
  • Information updates;
  • Error corrections on the user interface;
  • Introductory video included on the homepage.

We inform that we migrated our open source project to GitHub: pwa_technologies where you can find more details about the Fénix version.

Comments and suggestions are most welcome!

We archived the Web pages of the Portuguese Parliamentary Elections of 2015!

Last updated on August 30th, 2022 at 10:55 am

The Arquivo.pt made 4 crawls of Web pages related with the Portuguese Parliamentary Elections of 2015.

We had appealed to the community contribution by suggesting Web pages related with the Parliamentary Elections of 2015 in order to archive it.

We made 4 crawls, during and after the election campaign period, using the list of 127 Web pages suggested by the community, archiving a total of 2 802 407 Web resources, that occupy 274 GB.

It were collected Web pages such as the ones from the running political parties, news in the media about the elections, blogs, opinion articles, and satirical political Web pages.

The Arquivo.pt respects an embargo period of 1 year, and for that reason the archived collection will only be avaliable by the end of 2016.

However you can consult now some archived Web pages from the previous Portuguese Parliamentary Elections such as:

We would like to thank all the volunteers that helped with this initiative.
Now we need your collaboration suggesting Web pages about the Portuguese Presidencial Elections.
Can we count on you?

A first attempt to archive the .EU domain

Last updated on August 1st, 2019 at 02:35 pm

News updated on August 1, 2019.

Arquivo.pt (the Portuguese web-archive) performed an experiment to preserve .EU web sites.

The .EU domain is commonly used to reference sites related to Europe. The strategy adopted to archive the World Wide Web has been delegating the responsibility of each domain to the respective national archiving institutions. However, the .EU domain fails to fit in this model because it covers multiple nations. Thus, the preservation of .EU sites was not been yet assigned and undertaken by any institution.

RESAW is an European network that aims to create a Research Infrastructure for the Study of Archived Web Materials (resaw.eu).

Arquivo.pt performed a first attempt to crawl and preserve web sites hosted under the .EU domain within the scope of RESAW activities. This first crawl began on the 21 November 2014 and finished on the 16 December 2014.

We performed 2 more crawls of the .EU domain. All the crawls were indexed and became searchable through Arquivo.pt one year after its finish date. Moreover, we made available a prototype that enables focused search over the .EU crawls which demonstrates the simplicity of creating search engines that targeted specific collections through the usage of the “collection” search parameter.

Collaborations with researchers interested on studying the collected web data sets or crawl logs are welcome.
