<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal">Bit of a non-techie question - but one that is in our domain.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I'm making some updates to the UKETD_DC (UK eTheses and Dissertations) export plugin:<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The changes will be issued as a Pull Request on the 3.3 branch, and I will also be making them into a Bazaar package.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The file already contains some copyright information from the British Library (who were involved with creating the initial export format):<o:p></o:p></p>

<p class="MsoNormal">it also has the 'standard' EPrints statements:<o:p></o:p></p>

<p class="MsoNormal"><span class="pl-c"><o:p> </o:p></span></p>
<p class="MsoNormal"><span class="pl-c">I was going to leave all these statements in as-is, and not add any of my own - but ten I wondered if this was actually a 'correct' thing to do - or whether I should be adding any additional information?<o:p></o:p></span></p>
<p class="MsoNormal"><span class="pl-c"><o:p> </o:p></span></p>
<p class="MsoNormal"><span class="pl-c">Obviously it'll still be GNU Lesser General Public License v3 or later, but what about the two copyright statements? Do they already conflict?<o:p></o:p></span></p>
<p class="MsoNormal"><span class="pl-c">Any thoughts?<o:p></o:p></span></p>
