The following blog will reflect on the connections that I’ve made with course material covered weeks three to six. All material taught won’t be covered but rather a reflection of the key aspects and there connections throughout.
We took a look at metadata and how it can be described as data that is used to describe other data. For instance, in order to better comprehend metadata it helps to look at the different forms of metadata and how it adheres to everyday life. There are three definite types of metadata which is subsist: structural, descriptive and administrative. Structural metadata takes a look at the vessels of data so you can find data within data. An example of structural metadata would be that information found within a magazine while the magazine is the vessel of data. Descriptive data takes a look at the information within the data from an intellectual perspective by analyzing aspects of the metadata such as a document and how long it is and so on. Administrative data places focus on metadata which is private and/or public whether it looks at emails or phone calls of a company or government documents containing the metadata.
From metadata we moved on to look at the ways in which bibliographic metadata and internet metadata have come to be. Anglo- American Cataloguing Rules (AARC) is a descriptive cataloging method that was used prior to its successor Resource Description and Access (RDA) which is currently the standard method used to frame bibliographic data. RDA organizes descriptive bibliographic metadata in a structural format based on Functional Requirements for Bibliographic Records (FRBR). FRBR uses various ideologies to formulate a hierarchy when it comes to organizing bibliographic data as well as making connections amongst the data. When it comes to internet metadata there’s an initiative used known as the Dublin Core which ultimately links terminology that is used to describe internet resources.
Machine Readable Cataloging better known as MARC 21 is a format used to organize bibliographic data. When you look at a book there are different ways to interpret the information surrounding the various elements such as title, author and so forth. BIBFRAME will soon replace MARC21 as it is also a bibliographic framework that has evolved to make bibliographic descriptions more organized. While MARC21 lists descriptions BIBFRAME allows for information to be grouped together in a more abstract format with three core levels being work, instance and item. Tim Berners-Lee, inventor of the World Wide Web came up with the terms linked data as well as the semantic web which identify the way in which we are able to find data today. Linked data allows for data to be interlinked with other data allowing for that data to become more useful. While I’m on google I can type in Toronto Raptors and up to date information would be linked. The semantic web is a framework which allows for the use and reuse of data across different platforms. With the semantic web and BIBFRAME I find that more data about certain topics can be found because of the linked data that will draw together the various resources.
Application programming interfaces are codes which allow for software programs to connect with one another. The best way to understand an API is by observing one like the Google API. I for one primarily use my Gmail account for everything. With Google API it has been able to track my home location and work location with the use of google maps. I’ve never put my home location nor work location in google maps but because of the map software it was able to track my frequent locations. If I go into google while my email is open type in home or work google maps brings the exact location up. With such API’s existing it makes me think how strong software interfaces are working to make connections amongst one another without the use of a human involvement.
Six weeks into DITA and I must say all I can think about is how all the course material that we’ve learned thus far seems like a game of dominoes. From week one to where we were introduced to data and how it relates to information to week six where we learn to work with data and the various ways we can retrieve information from the web, databases and API’s. As every week goes on I realize the correlation with the material that we’ve learned in previous sessions and how it pertains to the LIS profession.
