+# LAKEsuperior Content Model Rationale
+
+## Internal and Public URIs; Identifiers
+
+Resource URIs are stored internally in LAKEsuperior as domain-agnostic URIs
+with the scheme `info:fcres<resource UID>`. This allows resources to be
+portable across systems. E.g. a resource with an internal URI of
+`info:fcres/a/b/c`, when accessed via the `http://localhost:8000/ldp`
+endpoint, will be found at `http://localhost:8000/ldp/a/b/c`.
+
+The resource UID making up the looks like a UNIX
+filesystem path, i.e. it always starts with a forward slash and can be made up
+of multiple segments separated by slashes. E.g. `/` is the root node UID,
+`/a` is a resource UID just below root. their internal URIs are `info:fcres/`
+and `info:fcres/a` respectively.
+
+In the Python API, the UID and internal URI of an LDP resource can be accessed
+via the `uid` and `uri` properties respectively:
+
+```
+>>> import lakesuperior.env_setup
+>>> from lakesuperior.api import resource
+>>> rsrc = resource.get('/a/b/c')
+>>> rsrc.uid
+/a/b/c
+>>> rsrc.uri
+rdflib.terms.URIRef('info:fcres/a/b/c')
+```
+
+## Store Layout
+
+One of the key concepts in LAKEsuperior is the store layout. This is a
+module built with a
+specific purpose in mind, i.e. allowing fine-grained recording of provenance
+metadata while providing reasonable performance.
+
+Store layout modules could be replaceable (work needs to
+be done to develop an interface to allow that). The default (and only at the
+moment) layout shipped with LAKEsuperior is the
+[resource-centric layout](../../lakesuperior/store/ldp_rs/rsrc_centric_layout).
+This layout implements a so-called
+[graph-per-aspect pattern](http://patterns.dataincubator.org/book/graph-per-aspect.html)
+which stores different sets of statements about a resource in separate named
+graphs.
+
+The named graphs used for each resource are:
+
+- An admin graph (`info:fcsystem/graph/admin<resource UID>`) which stores
+  administrative metadata, mostly server-managed triples such as LDP types,
+  system create/update timestamps and agents, etc.
+- A structure graph (`info:fcsystem/graph/structure<resource UID>`) reserved for
+  containment triples. The reason
+  for this separation is purely convenience, since it makes it easy to retrieve
+  all the properties of a large container without its child references.
+- One (and, possibly, in the future, more user-defined) named graph for
+  user-provided data (`info:fcsystem/graph/userdata/_main<resource UID>`).
+
+Each of these graphs can be annotated with provenance metadata. The layout
+decides which triples go in which graph based on the predicate or RDF type
+contained in the triple. Adding logic to support arbitrary named graphs based
+e.g. on user agent, or to add more provenance information, should be relatively
+simple.
