Learning object is a digital file intended to use for pedagogical purposes. 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.
Meta-DataA structured description of characteristics such as the meaning, content, structure & purpose of a resource • สรุปการปฏิบัติการที่จำเป็นสำหรับผู้ฟังของคุณ • สรุปรายการปฏิบัติการที่ต้องติดตาม The dominant purpose of learning object metadata is to increase the effectiveness of retrieval systems.

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. • Develop the search interface. • Use test the search interface. • Deploy the search interface.
