hello=2C=20
i am building a e-business web site and always be frustrated by the continu=
ously changing database schema requirement=2C
that why i consider to use ARC to make my designing flexible and more easy.=
Thanks for the wonderful ARC project and the wonderful idea.
anyway =2C i still have 2 basic questions:
(1) firstly i want to build my own ontologies(schema) for my application an=
d import them to the ARC rdf store=2C then my web application will=20
create many instances on vocabulary of those ontologies and also be sa=
ved to the rdf store.=20
my question is:
on account of my ontologies continuously changing=2C eg. sometimes i n=
eed add some vocabulary or sometimes i need remove some
vocabulary from my ontologies=2C is that posible for ARC? if i can ad=
d or remove vocabularies from my ontologies=2C how about the exist data?
i mean=2C do the instances in my rdf store will automatically synchroni=
zed to the new changed ontologies? how?
(2) my web application used transcation of mysql=2C AFAIK=2C the myISM tabl=
e could not support transaction=2C and i noticed that the tables of ARC2
use myISM table=2C could i change them to use innodb tables?
thanks in advance..
