make it easier to get going

[bblfish]

Some ideas:

• releasing eye on https://brew.sh to make it easy to install so that it installs swi-prolog would make it much more accessible to people on macs.
• a little better documentation on how to get going.

One thing I used Cwm for was just so that I could use the nice n3 syntax to write things that were not possible to do in n3. So I have a foaf file that used the = shortcut so that one could name blank nodes, see the use below...

I then have a little script that translates it to rdf/xml and turtle and from there to ntriples even.
I can use rapper to do translations from turtle. But I think there should be a way to extract at least
NQuads from a tool such as eye.

So with cwm I would

cwm card.n3 --rdf > card.rdf
rapper -i rdfxml -o ntriples card.rdf  > card.nt
rapper -i rdfxml -o turtle card.rdf  > card.ttl

So I worked out that the equivalent for eye was

$ /opt/eye/bin/eye --nope  ~/Documents/card/card.n3 --pass > out.ttl
$ rapper -i turtle -o turtle out.ttl > card.ttl

that gives me the turtle nicely formatted but I still have the owl:sameAs' everywhere.

Could you elaborate on what is wrong or broken in the output of EYE

$ eye --quiet --nope card.n3 --pass 2>/dev/null

You can always use the following rule

$ cat rule.n3
@prefix owl: <http://www.w3.org/2002/07/owl#>.
@prefix log: <http://www.w3.org/2000/10/swap/log#>.
@prefix e: <http://eulersharp.sourceforge.net/2003/03swap/log-rules#>.

{   ?S ?P ?O.
    ?O e:label ?L.
    ?O = ?A.
    ?O ?B ?C.
    ?B log:notEqualTo owl:sameAs.
} => {
    ?S ?P ?A.
    ?A ?B ?C.
}.

to get the extra triples

$ eye --quiet --nope card.n3 rule.n3 --pass-only-new 2>/dev/null

One should continue the [ = discussion in #43 .

Then this issue can be just about making the release of eye easier, by publishing it on brew. (That would fit the title better :-)

[josd]

If I do it, I also have to test it on MacOSX but I don't have that.
For easy installation you could use https://hub.docker.com/r/bdevloed/eye/ which is up to date.
Maybe someone could do a similar project for brew?
