sounds  like engineering ....    (03)

I am evaluating  ontology repository architectures, in fact, I am
trying to work out how can the concept of ' centralized repository'
be reconciled with the notion of 'linked data model' , my conclusion
so far is that a repository cannot be centralized without conflicting
with the core notion of distributed model as the LDM, not without
convolution   the web is the repository for ontology, if we have the
right representation and querying mechanisms, and thats a central idea
to the semantic web. But maybe your approach is distributed?    (04)

there are several tools/environments being built to support various kinds of
ontological data viewing, editing and querying ,    (06)

isn't that what Tabulator is supposed to do? I have heard of
rhodonite, and brown sauce have similar functions
search for 'URI browser'  or 'rdf browser' - they are designed to
interact with data expressed as rdf, but i am not too sure about what
level of granularity (level of fragment) they support, please let us
know what you find out if you look into it    (08)

However, if you have a specific interface or functional requirement in
mind such as import/export of individual fragments, or how the value
of the fragment should be displayed/visualized and stored (make local
copy tc), please specify it so that we use it as input for further
development of products    (09)

i dont think machine has such preferences...:-)
but for humans it should be easy to have a friendly tag masking the
ugly uri syntax, if the hash bothers you    (011)

there exist a few, thus at different stages of development and
flavours, and each with their own set of quirks    (013)

please share your findings..    (014)
