[tycho-dev] What is mean by artifact.size in artifact.xml generated insi

[Kasun Siyambalapitiya <kasunsi@xxxxxxxx>]

Hi all,

I am trying to understand how the p2 plugin actually works and tried a small scenario where few features and bundles were installed to the p2-repo. When the p2-repo generation was successful I found out a`artifact.xml` file located inside the artifact.jar. ( please find my artifact.xml below).

By observing the details, I was able to found out that   <property name='download.size' value='10222'/> is showing the actual size of my artifact while <property name='download.contentType' value='application/zip'/>  is showing the type of the artifact. What is shown by  <property name='artifact.size' value='4096'/>  ?

Why is it simillar in most of the entries?. 

Thank you,
