Article Summary #7: How Local Librarians Can Impact the Digital Asset Management Industry, A LS566 Post

Image from Article
Anthony Myers in How Local Librarians Can Impact the Digital Asset Management Industry explains that digital repositories are a type of library because of the way digital assets are stored and how they should be organized. David Diamond, director of global marketing at Picturepark, believes that librarians should reach out to DAM vendors to offer aid. The setup of a DAM system is very important because it can get very messy if not done properly. So having the solution of librarians in DAM setup makes since. Librarians work on organizing information so they would know how to organize the digital assets (proper terminology, definition, etc) to make accessing them possible.

This connection makes a good deal of sense; as Diamond states, "DAM is a library if you think about it." Organizing is more, let's say, complex than just storing (think of all those 'how-to-organize' book in bookstores), besides what would the point be of having a digital asset if it was impossible to find. It's a connection that not a lot of people would make, but it's a connection that makes a lot of sense.

Random Musings for LS 566

Random thought process - GO!

How does one name the publisher of a digital-born object?

For a book it's easy - look at the title or title verso and it's usually listed there. But a digital-born object like a digital scanned photograph does not have a title or title verso page. Cue the 'hmmmmm' and thinking induced chin stroking. According the Dublin Core Metadata Element Set, the publisher is "[a]n entity responsible for making the resource available."

I thinking..............
So how is a digital photograph made available? My first thought was it can't be the photographer because he made/took the picture so that person is more along the lines of creator. My next thought was, well who handles the upkeep of the digital photograph? Electronic things to not react well to benign neglect like many physical objects do.The entity that hosts the digital photograph is the one that makes it available for people to view. So we could  make a case that they are the publisher.

Does that make sense? I think it does.

Article Summary #6: Image Retrieval, a LS 566 Post

From the Article
Abebe Rorissa discusses in Image Retrieval: Benchmarking Visual Information Indexing and Retrieval Systems how, even in this electronic age, a picture is worth a thousand words. People shares images and videos online on many websites. Because of this popularity he poses the question: What is the current status of images and video indexing and retrieval? He covers three main issues: firstly, efforts have been made to automate the process but it is highly limited; secondly, there are a lot of images out there but little organization with it; thirdly, there are challenges in analyzing the images that come from various domains. Rorissa goes over two approaches to indexing and retrieval: concept-based and content-based. Concept-based relies on people to manually index while content-based is automated using color, texture or shape to organize. He stresses that a combination of the two should be adopted as the best approach in indexing and retrieval. He also touches on how for videos query-by-content is the preferred retrieval method. A lot of strives have been made but improvements have to be continuously made to make indexing and retrieval better.

This article was written ten years ago to the month. As I've mentioned before that is in dog years for anything electronic. But the points that Rorissa makes are still valid today. Improvements have been made since this publication and improvements are still continuously being made. I am guilty of what he mentioned, taking lots of pictures, dumping them on my computer, then taking more pictures without organizing them. My computer organizes my pictures by the date they were taken so it's not a complete mess. It will be interesting to see how this will develop in the future and maybe someday there will be a standardized method like Dewey for books, but for images and videos.

Article Summary #5: Digital Preservation Metadata Standards, a LS 566 Post

Image from Educopia Institute
Angela Dappert and Markus Enders in Digital Preservation Metadata Standards discuss metadata within digital repositories. Digital repositories do not just act as a preservation tool for digital objects. They do everything from ingest information to providing access to that information with everything in-between. Repositories also actively work to prevent loss of the data in their care. Metadata is key to the preservation functions. There are several types of metadata that Dappaert and Enders split into four categories.

Description which describes the intellectual entity through properties. Structural which deals with the physical and logical structural relationships. Administrative which is about who handles the care of the digital object(s); it is also referred to as Preservation Metadata. Each of these categories are expanded or combined with another category to create the different standards used in Digital Repositories, i.e. LMER, PREMIS, METS, MPEG-21, and Z39.87. Dappert and Enders explain that there are so many options and the field is still relatively young to set any metadata standard in stone.

Reading this article just made the final piece click in my head how mind boggling complex metadata can be. It's a 3D puzzle with hundreds of possible solutions. I feel like I should sit down with each standard method and spend a week studying each of them. Maybe a week and a half. I do like the fact that they point out that this is still a developing and relatively new field, a fact that I think slips peoples minds because we are so accustom to technology. There are many points in different standards that have to connect to other standards to be able to be shared and, given how many standards there are available, is a massive undertaking.

Article Summary #4:Preservation Challenges in the Digital Age, a LS566 Post

Bernadetter Houghton, in Preservation Challenges in the Digital Age states right off the bat that "the digital preservation field is evolving rapidly." With such a quickly changing field there are many challenges, especially due to the nature of the digital object. Houghton lists different areas where the most common of challenges tend to show up: multiplicities, hardware and storage, software, legalities, metadata, and privacy to name a few. There are different aspects of digital preservation that do not come up when dealing with a physical object. Not only to archivists have to keep an eye on the things of the past but also keep an eye on the things to come. Change happens, it happens a lot and the best way to deal with it is to make the best educated guess on what will come and on what is best to preserve.

Houghton give an excellent overview on many things that come into play with digital preservation. As she pointed out there are many different challenges that come with each method that is used. The biggest problem is when things become obsolete or crash. I am one of many people who has suffered the blue screen of death and lost all my data. Twice. A blue screen of death is the absolute last thing anyone would want to happen to a large digital collection. I understand how important it is to make sure that there are steps and processes in place to avoid any loss of data, because once it's gone, it's gone.

Planning for Metadata, Article Summary #3, a LS 566 Post

Jody Perkins in her article, Planning for Metadata, gives an overview into what it takes to work with metadata. She explains that the creation of metadata requires planning. It cannot be done haphazardly. While designing metadata one has to keep in mind the interoperability issues and what to about about it without affecting the quality of the collection. Collections have to be reviewed and mapped out. Perkins, based on her experience, explains four parts of metadata design: "Evaluation of project collection and associated metadata, review of current standards,  review of other relevant collections, and documentation of decisions related to the selection and implementation of standards."

This article was written about ten years ago. Ten years is like dog years in terms of technology with how everything changes so fast. But the process that Perkins lays out in her article is still relevant today. Things have to reviewed and researched before anything can be implemented in any form. Perkins gives a list of guidelines for standards that I found very helpful (the links are still valid, another plus). There is also a checklist, 'Collection Evaluation Checklist for Metadata Planning' that is well thought out and I am planing on referring
to it for any collection I may work with in the future.

Metadata, Numb3rs, and Library School

I've tweeted about this before and I thought I should expand upon it. My first introduction to the concept of metadata was not in class for Library Science. It had first crossed my attention on the show 'Numb3rs'. For those of you who don't know it's a crime show about tow brothers, one is a genius mathematician the other is a FBI agent and together they solve crimes.

Yes, they solve crime with math.

As a result, concepts like metadata and datamining were shown being applied in a real world format. It helped ground these cerebral concepts in a fun way. It's a fun good show that I highly recommend. The prided itself on keeping the math and its application correct (there were some liberties here and there for the sake of story - but overall, real solid).

It's a bit like going in reverse for me - seeing real world application then learning about the theory.

Metadata is still a little daunting, but knowing and seeing an application of it makes it less so. In the end I can say that yes, I did learn something by watching TV.

Metadata for All: Article Summary #2, A LS 566 Post

From the Article
Mary W. Elings and G√ľnter Waibel in their article Metadata for All: Descriptive Standards and Metadata Sharing Across Libraries, Archives, and Museums discuss integrating digital content in libraries, archives, and museums, and the challenges there in. There are different standards used in regards to handling digital content. They go over the key concepts for the different standards, like data field and structure, and data forma. With each concept they give an example of how it works within the standard method. There is a helpful table (see image) explaining which standards are used in each field. They point out that the success of this endeavor hands on the development of a "homogenous practice in describing like-materials in different institutions."

I am all about across the board standards. It makes sharing and preserving data effective and efficient. Plus the risk of something getting lost in the shuffle is reduced. I would also like to point out that there an awful lot of acronyms in this article (the field in general -we're all speaking in tongues at this point). Despite the article being ten years old, the section on current trends was informative and still relevant. There is a constant need to stay current, especially with the new technology that is always coming out. Library Science is always updating itself so that need of standards is vital.

The Play that Goes Wrong performing at The Royal Variety Performance 2015

I haven't laughed this hard in a long time.


Big Metadata Article Summary #1, A LS566 Post

"We kill people based on metadata." - Michael Hayden

The above (and completely unexpected) quote illustrates the massive importance of metadata and how it can be used. Allison Jai O'Dell in her article, Big Metadata: Mining Special Collections Catalogs for New Knowledge talks about how special collection catalogues are full of metadata that can be used for research. But for that to happen the catalogues have to be thought of as big metadata which in turn can be data mined. She points out that it will be a lot of work but the information is there and it just have to be organized.

I have never really thought of library catalogues as a form of metadata before, but it does make a good bit of sense. The aforementioned quote, which comes from the article, made me do a double take, but after the second reading I realized that Michael Hayden was correct. A lot can be learned of someone by the information that is innocuously put out everyday.
