Linked Data in the RDF model<br>
solves crucial challenges for Solid.

<ul>
<li>
If we all store our own data,<br>
how do we <a href="#linking">connect</a> it to others’ data?
</li>
<li>
How can apps <a href="#semantics">share</a> data,<br>
without too many prior agreements?

<li>
How do we <a href="#integration">integrate</a> data<br>
from multiple data pods?

Through URLs and RDF, every piece of data<br>
