Damaged files and Questions

Damaged Files

Unfortunately some of the clean files wouldn’t open on the computer I was using so I couldn’t really compare all of the undamaged files with those I damaged, but was able to see that the word file lost all of the diagrams when it was damaged.

The damage to the PDF file resembled the image damage more, with blocks of black and grey appearing over some of the diagrams.  The computer recognised there was damage to the file and warned me of this before I opened it.

Of the image files, the TIFF file seemed to suffer little damage when I ‘shot’ it, but when I corrupted it the image the damage really showed.  The Tiff file and the JPEG file, though very obviously damaged, would still have been readable, however the PNG and GIF files were completely undecipherable.

 

3 Questions

  1. On March 11, 1968, President Lyndon B. Johnson mandated that all computers purchased by the United States federal government do something. What was it?

A. March 11 – U.S. President Lyndon B. Johnson mandates that all computers purchased by the federal government support the ASCII character encoding.

 

Google search “march 11, 1968, president lyndon b. Johnson” – answer via http://en.wikipedia.org/wiki/1968_in_the_United_States  “1968 in the United States”

 

  1. The vigesimal system was memorably employed by a U.S. president when dedicating a cemetery. Which president, and what decimal value did he express in vigesimal notation?  Hint: in Old Norse, a notch on a stick used to tally values in vigesimal notation was called a “skor.”

A. Four score and seven years – Gettysburg Address

 

Google search: vigesimal – and found that it meant base 20 numeral system so knew it was the  Gettysburg Address – but hadn’t known it was a dedication ceremony for a cemetery!  – Looked Gettysburg Address up on Wikipedia to check the exact quote!

 

3.  freeformatter-output

A.  ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/

 

Wikipedia search on “base 64” which gave the answer.

 

I know I seem to have put my faith totally in Wikipedia, but I do really like Wikipedia!  I know that it can be unreliable but if I wasn’t sure I would check the facts via other sites.  For example once I knew the answer to the base 64 question via Wikipedia, I checked again via a few other sites and got the same result!

British Pathé archive blog

My main area of interest in archives, lies with moving images.  If a picture is worth a thousand words a moving image must be even more verbose, add sound and you won’t get a word in edgeways.  The sheer variety of subject matter held by British Pathé is endlessly entertaining and informative.

So here’s the link http://britishpathe.wordpress.com/

And here’s the link to the material on Scotland they posted in relation to Independence http://britishpathe.wordpress.com/2014/08/15/scottish-independence/

And here’s a link to ‘a sample of some of the finest 20th century reporting on Scotland’… Ye never know ye might see yer Maw! http://britishpathe.wordpress.com/2014/09/15/a-celebration-of-scotland/

Context

Group 1 was asked to discuss the concept of context in terms of archives and record management.   As context is a significant factor in considering all the concepts we discussed in our debate, we decided to each take one of the other five terms, and write a few sentences on how context relates to them. Graham also wrote a introduction on context.

Graham – Context To describe the context of something is to describe its relationship to the wider environment, physical, intellectual or temporal, in which it originated or exists.  Without understanding this relationship it would be impossible to understand an object or thing itself. Nothing, whether physical objects, which are defined by their differences from and interactions with other objects, or texts, which consist purely of symbols meant to describe and invoke the image of something other than itself, would have any value or have any meaning beyond their physical appearance if they were considered in absolute isolation.

Edith: Context – Value Value is arguably all about context. The value of a record will depend on its audience, and for what purpose that audience utilise said record. Such values could range from a record’s legal implications for a business to directly emotive and political outcomes – including the shaping of identity and collective memory.

Claire: Context – Format /Layout Context and format are very closely linked; so much so that I would suggest that they are in fact interdependent on one and other in regards to how we read and develop a fuller understanding of a record. Whilst context can be described as the unique set of circumstances that lead to the creation of record; format is often the key to our understanding of it, as it can organise the content of a record in such a way that it is able to convey context. For example, a letter written on headed paper, that includes addresses, a formal greeting, and a seal, could imply that it is in fact a formal record of some significance and authority. The format of a record is decided not just by its creator or creators, but also by accepted conventions of the context that it was created in.

Elizabeth Shepherd and Geoffrey Yeo, Managing Records: Managing Records: A Handbook of Principles and Practice, London: Facet Publishing, 2003, Ch.1.

Kate: Context – Authority/Authenticity Authority validates the integrity of a record. The provenance of a record may include errors, intention to deceive, plagiarism or corruption. When acknowledged these characteristics can amplify confidence and trust; therefore the authenticity of the record. The authority of the record permeates our understanding of all aspects of its context.

Graham: Context – Purpose All artificial objects, such as texts, were consciously created for a specific purpose and are defined by them, whether it is to be used directly or to convey information. It is difficult to appraise the significance of an object or text without understanding its intended purposes, as that will dictate its relationship to its environment. While the purpose of many objects or documents may seem self-evident, explicitly so in some texts, a better understanding of it may require knowledge of who created the text or object, and who was its intended user or audience and thus of the technological, cultural and linguistic conventions and restrictions of their time and place. It must also be considered whether this text or object was intended to be used or experienced by itself or was part of a larger whole. The purposes of some documents or objects may be ambiguous or contrary to what they first appear, which has led some theorists to believe that the interpretation of those viewing the object is is more important than its intended purpose. However, attempting to understand the purpose behind an object or text creation is essential to assessing its reliability, and to investigating the nature of its creators.

Ursula – Context – Audience Context is key to the relevance and usefulness of a collection, and the records within it, to the audience. Essentially, does that collection or record satisfy a need (for information, service, evidence, memory etc) that they have? E.g. The minutes of a bank’s AGM from the 1950s – can for the bank form part of it’s corporate memory; for a student of gender studies, provide evidence of the changing role of women in business; for an economic historian, help to plot changing business trends, but to an average member of the public may hold no interest whatsoever.

Hello Fellow IMPs,

Well as I declared at the session on Thursday, I’m not wildly keen on blogs, so the idea of writing abut myself and contributing to this blog fills me with an element of dread.

However I also know that skills involving Social Media and Blogs are almost routinely asked for in job profiles these days, so regardless of my personal feelings, I can see the value of this exercise and will be a willing participant. Who knows? Maybe I’ll change my mind!  So here goes…

My background is mainly in academic libraries, and film & video archives. I’ve had 10 years experience in various Higher and Further Education Libraries in Ireland, England and Scotland, in the role of Library Assistant, and 8 years with the Information & Archives department of the BBC and BBC Scotland as a Preservation Cataloguer, then as Librarian and finally as an Archive Media Manager.

In between the work, I completed a part-time BA Hons in Information Management & Library Studies at Brighton University. Brighton is a great place to live and study. I also worked in a pub there while studying, and if you get the opportunity to do so I would recommend it as a confidence building exercise, really!

I loved working with moving images and would love to continue to do so in the future. However part of the reason for taking this course is to broaden my outlook and learn more about the record keeping and business archive world generally.

I know this 9 months (I’m only doing the Post-Grad Diploma) is going to fly, so I’m planning to get as much as I can from it, before hitting that job market again (eeek). See you in class!
