I have been coming across information about Merkledags and IPLDS that seems conflicting or overlapping.
When I first started looking into IPFS I quickly learnt about Merkle trees and how IPFS uses a slight modification of that…instead of trees, we have DAGs, hence the Merkledag. The link about Merkledag on the documentation here https://docs-beta.ipfs.io/concepts/merkle-dag/#further-resources basically presented it as the underlying data structure of IPFS.
I think I recently came across a section of the docs (and for the life of me I can’t find the link) where it was stated that Merkledag are being deprecated in favour of IPLD. But even without finding a reference to that claim, the first texts on the IPLD website here https://ipld.io/ states that IPLD is the data model of the content-addressable web - but is that what the Markledag is supposed to be?
I will appreciate if someone knowledgeable about these concepts can help clarify and disambiguate between Markledags and IPLD and how they fit into IPFS.
