The role of Information manager and Information flows at the moment

Even though the practice of metadata were changed from catalogue cards to machine-readable formats, for a long time metadata information is stored in repositories as electronic records. During the recent year, the World Wide Web is moving from the web of documents to the web of data. The metadata information is moving from merely machine-readable towards machine-processable, where it is essential to break the record and repository silos and make data (especially metadata) into machine understandable pieces. We present information about the data using the RDF (Resource Description Framework) which provides a data model for presenting metadata as machine-understandable and –processable triple statements (i.e., subject, object, predicate). For example, Adam (subject) is from (predicate) Peru(object). The subject of a triple is the URI (Uniform Resource Identifier) identifying the described resource, a predicate is the existing relationship between subject and object, and an object is a literal value or the URI of resources that is somehow related to the subject. In the above example, “Adam” is a person and “Peru” is a country. Although they represent totally different metadata, they are linked through the predicate (properties) and made it possible to gain the data and information from Adam to Peru such as the population, environment, currency, culture etc. of Peru. Furthermore, the information will be connected into the Linked Open Data (LOD) cloud where anybody can join, put their data and access the others information. This can be used by UN organizations, and play the role of one family for providing the services to the world. The linked data will have an impact on e-science, e-government, and e-agriculture.

The roles of information managers have changed due to this movement. The classical information mangers managed the information in order to be findable or searchable in the context of records in a small or large silo. Nowadays the information managers will need to manage the information in order to make it to be accessible, exchangeable, useable, reusable in context of data that are semantically linked, far beyond the boundary of repositories or silos, and far beyond bibliographic data. In my opinion, in the next five years more metadata and raw data will be liberated from silos and join the LOD cloud. The agriculture data will form its own cloud, interacting with other scientific data, geographical data, government data, and social society data. Here metadata is critical for the overall quality of their interaction and reuse. On the other hand, not every current Semantic Web technology has a clear implementation guideline; different models and tools are invented by implementers each month. This is very challenging because it requires information managers to be able to understand the whole landscape and master the technologies quickly and correctly. It is also the new role of the information managers to compare different approaches, identify good practices, and contribute to best practices through their own work

The year 2011 is a personalization of Web

The 2010 was the year of Linked Open Data. Most of the organizations introduce their data in the web as RDF format by breaking their old databases. I think, this year will be more agent based approach for the web. For example, I am in Peris and I would like to get more information about hotel, food, people, night clubs etc from the web. I was working the project "visit findland". It was a primary steps to make your own travel plan by using 2nd generation web technologies. I am expecting this work will continue further in this year and coming years and make people life more easy.

my visit to Stanford University

It was my dream to go to Stanford University. As I always try to follow my supervisor footstep. I started to my journey on 13th of October behind my beloved Nargish at Rome. It was terrible moment in my life to say goodbye to her. I had to do it because I wanted to explore my experience.

I arrived the special Terminal 5, a special terminal for USA flight. Very tight security. After crossing the security, I got into the plan and landed at Philadelphia International Airport. The immigrant officer asked me several question at least 45 min and gave me a seal to my passport to enter the USA. Again flight to San Francisco L. At last I arrived to Stanford Gust house. The Guest house was very nice.

On 14^th , I got up from my bed very early and took my breakfast. I came to know that there was very nice shuttle service for Stanford Campus. I got into the Shuttle and got down in front of the Lab. The Lab Secretary gave me the schedule of meeting with Professor and researchers. Meanwhile, I met two visiting fellow from Germany, Austria. First day, I had a wonderful time with them.

Later on, I met with Professor Mark Musen. He was so kind human being and explained me lots of their work. I also showed my work. He appreciated the work. I also met with Natasha Noy (a key person of Protégé tool, bio-medical ontology). She showed me the work of ICAT, a web-based frame work for protégé tool. They have developed this frame work for WHO. I wonder to see their work. It is similar work that we have done. But, our work has been started at FAO since 2005. It shows the importance of our work. It was also wonderful to work and chat with Timothy Redmond.

I got a little change to visit the campus beside my work. It was amazing environment. I wish I could study in here J. Now, I understood why they are different from others. It is a place for study.

cooking and spending time

I was so busy and stress the last couple of days that I could not do anything in my workplace.

Agrovoc OWL to SKOS

Today, I got a news that our paper is accepted at

http://www.comp.glam.ac.uk/pages/research/hypermedia/nkos/nkos2010/

I am extremely happy.. Now, I am preparing for USA on-line teaching at University...

Keep my finger cross for visa... !!

DC2010 paper

I have just got the news that my paper has been selected in DC,2010, USA. I am extremely happy for this. I hope that I can enter the scientific community soon.

URI VS URL

some of my colleagues asked me about the URI Vs URL. I was thinking to make it clear for everbody. Here is my explaination:

URI:
A URI identifies a resource either by location, or a name, or both. More often than not, most of us use URIs that defines a location to a resource. The fact that a URI can identify a resources by both name and location has lead to a lot of the confusion in my opionion. A URI has two specializations known as URL and URN.


URN
A URI identifies a resource by name in a given namespace but not define how the resource maybe obtained. This type of URI is called a URN. You may see URNs used in XML Schema documents to define a namespace, usually using a syntax such as:



URL
A URL is a specialization of URI that defines the network location of a specific resource. Unlike a URN, the URL defines how the resource can be obtained. We use URLs every day in the form of http://damnhandy.com, etc. But a URL doesn’t have to be an HTTP URL, it can be ftp://damnhandy.com, smb://damnhandy.com, etc.

In the last word, we can say that URI is identifier of resource and URL gives us information to obtaine this resource.

if URL present our homepage then each object can be retrieved from the homepage by using the URI ( ex. URL and URI of Ahsan (www.ahsanmorshed.bloger.com and ://ahsanmorshed.blogger/ahsanmorshed )
