where each of the factors weights from 0 to 100%, so that MELODA ranges from 0 to 10. Further explanation about MELODA assessing process is included into annex 7.1.3.

Here there is one example of the assessment process with MELODA 2.5 metric.

Step 1: Legal assessing: Level 4 Step 2: → 90% (Commercial use)

Step 1:Technical assessing: Level 4 Step 2:→ 75% (Metadata without details)

Step 3:
