Learning Management System(LMS) ia a software application that manage the deployment, management,and traking online learning resources.LMS use database for storing information about learner and courses.

Learning object is a digital file intended to use for pedagogical purposes.

Meta-Data A structured description of characteristics such as the meaning, content, structure & purpose of a resource

Developing a Metadata Strategy

Stages of building meta-data.

Stage 1: Select a small number of meta-data fields. Create a document template for a meta-data entry form. Create a simple meta-data review process. Create an empty XML meta-data record that contains only the fields

you have selected using the IMS DTD or XML-Schema. Create one complete sample form with meta-data values in every field

you have selected. Review the meta-data. Adjust if you must. Teach someone how to move the data fields from the form to an empty

XML record using an XML editor. Make a directory linking record file names to module titles. Store the resulting XML record. Write a meta-data entry instruction guide for your users. Make a small library of XML records.

Stages of building meta-data.

Stage 2: The data base. Define the searchable record. Will it be a few fields or a few

buckets that aggregate fields? Create the database record structure. create a method for mapping or aggregating the XML record

fields into the data base records. Populate the data base from the XML library.

Stage 3: Searching the data base.

1. Develop the search interface. 2. Use test the search interface. 3. Deploy the search interface.

1.Database /meta-data?

2.Select the fields

3 . A sample Meta-Data entry form
