Cerf rocks

After I wrote about digital preservation and the need to save everything, not just the so-called “important” stuff, Jason wrote a lovely piece with his own thoughts on the matter:

In order to write a history, you need evidence of what happened. When we talk about preserving the stuff we make on the web, it isn’t because we think a Facebook status update, or those GeoCities sites have such significance now. It’s because we can’t know.

In a timely coincidence, Vint Cerf also spoke about the importance of digital preservation:

When you think about the quantity of documentation from our daily lives that is captured in digital form, like our interactions by email, people’s tweets, and all of the world wide web, it’s clear that we stand to lose an awful lot of our history.

He warns of the dangers of rapidly-obsoleting file formats:

We are nonchalantly throwing all of our data into what could become an information black hole without realising it. We digitise things because we think we will preserve them, but what we don’t understand is that unless we take other steps, those digital versions may not be any better, and may even be worse, than the artefacts that we digitised.

It was a little weird that the Guardian headline refers to Vint Cerf as “Google boss”. On the BBC he’s labelled as “Google’s Vint Cerf”. Considering he’s one of the creators of the internet itself, it’s a bit like referring to Neil Armstrong as a NASA employee.

I have to say, I just love listening to him talk. He’s so smooth. I’m sure that the character of The Architect from The Matrix Reloaded is modelled on him.

Vint Cerf knows a thing or two about long-term thinking when it comes to data formats. He has written many RFCs for the IETF (my favourite being RFC 2468). Back in 1969, he wrote RFC 20, proposing the ASCII format for network interchange. If you’ve ever used the keypress event in JavaScript and wondered why, for example, the number 13 corresponds to a carriage return, this is where all those numbers come from.

Last month, over 45 years after the RFC’s original publication, it became an official standard.

So when Vint Cerf warns about the dangers of digitising into file formats that could become unreadable, I think we should pay attention to him.
