Who are the intended users of GDL?
Digital library is very broad. It is depended on the community that use it. As long as the community has users, GDL can be used for them. It can be used directly or you do some modification such  as on interface, font, color, etc that fulfill your users' need.

What kind of resources can be managed by GDL?
GDL can manage any type of digital resources, such as:

  • text
  • image
  • audio
  • video
  • software

Unfortunately GDL doesn't touch the resources. It only receive and store them in a file systems, and make link from their associated metadata. GDL will create metadata for each resources, and start to work on this metadata - index, search, disseminate, displey, and so on.

What services are needed to run GDL?
You need Apache, PHP version 4 or above, and  MySQL. It is very important to check your PHP.INI file and modify according to GDL's need. There are some unusual setting for PHP.INI that it need.

How to access collection in a GDL server?
You can access using searching and browsing the collection. The method should be intuitive if you familiar enough with Yahoo, Altavista, or other directory and search engine.

Do I need to register to a GDL server to download the files?
Yes, you have to register to DOWNLOAD the files. If you only want to search and browse, the login  is not required.

How to activate my account?
After you fill the registration form, an email should be sent to your account. But, it happen only if the GDL server using SMTP and activate the email sending. Follow the instruction in the email, or input your email and activation code at GDL server web page.

If you didn't receive email, you must ask the administrator to activate your  account.

There are so many GDL server. Shall I register to all of the servers?
Practically, No. You didn't need to go to other GDL servers as long as your GDL server has download/harvest all metadata collections from other servers. You can search and  browse other GDL collections from your own server. If you need to download a file, your server will tell your login session to the server that store the file, so you don't have to  login again.

But, if you really have to visit other GDL servers, for this time you have to register again.

What is the different between GDL 4.0 and GDL 4.2?
GDL4.2 is developed using standard of application development (analysis, design, implement, testing). The code adopt the object oriented concept, so others developers can reuse the classes to develop their application with own enviroment. The other things in GDL4.2 is support to change the theme easilly

The features are most likely same. The main different is that GDL 4.2 try to adopt Web2.0 standard, they are RSS and Folksonomy.

How to migrate my existing database from GDL 4.0 to GDL 4.2?
It is very easy to answer. Just consult our GDL manual or you can contact KMRG team for assits.

What is the meaning of metadata?
Metadata is a piece information about a data. It is data about data. It is not the real data that you need. For example, you need a data, in the form of file about medical. The metadata will give you information about its title, author, abstract, and links to that file. So, I hope you get the idea.

What is the different between metadata and data?
It is different. Read above description. But some time metadata = data. For example, if I put my data containing a news into a metadata, so the metadata will become data. Because what I need is there.

What is the example of data in term of GDL?
Data in GDL could be a file of theses document, a file of my picture, a file of my voice, or a file of my video when I am bicycling here. In GDL, each metadata will refer to one or more files. But sometimes the administrator is too lazy so he only put metadata without any files. Don't be disappointed because of this. Oke?

So, there are two types of object in GDL namely metadata and files?
Yes.

How GDL manages metadata and its associated files? Metadata will be stored and managed in database. While the files will be stored in a file system. Metadata contains links to its associated files. So, when you read a metadata, you also will be pointed to the files it described.

Does GDL support networking among GDL servers?
Yes.
