Link Life / Ownership
by Gary Mazz 06 Sep '10

06 Sep '10

Hi, I'm working on an implementation of the new link model. The link represents a relationship between two resources. The relationship can only exist if both resources exists. If either resources are deleted, the link is no longer valid an should be destroyed. Is this correct ? cheers, gary

Re: [occi-wg] Link specification
by Csom Gyula 02 Sep '10

02 Sep '10

Hi, some notes: [1] action on resource delete The working draft specifies the behaviour of deleting links (ie. "An OCCI server MUST NOT delete the associated Resources upon receiving a client DELETE request for a Link."). It's counter part should be also defined, ie. the behaviour of deletion of associated resources. Should the server automatically delete links, as well (CASCADE DELETE behaviour)? Or should it prevent from deleting a resource, if there's a link pointing to it? Or should it be configurable either per link instance or link type? [2] reverse links It might be useful to provide a so called 'reverse link' service, too. Ie. one should be able to query the links that points to a specific resource. Or formally: reverse_links(r) := {link | link.target = r}. In order to? Well, querying reverse links is a common task. For instance: to see what computes belong to a given network... Why... since someone can list all links then filter out the unwanted ones? Within a large system this could be a slow and resource-intensive operation. Meanwhile the cloud system could work from its internal index to filter the necessarry links which is much more faster. This might be modeled as either a new attribute (ie. adding reverse_links to Resource or kinda) or as a special query service (GET /reverse_links/$resource_id HTTP/1.0 or such). [3] built in link types The working draft enables subtyping links: "An OCCI server MAY enforce additional attributes at creation time if the link has been subtyped using additional categories." Sample from the wiki: Category: link; scheme="http://schemas.ogf.org/occi/core#", disk_drive; scheme="http://example.com/occi/link#" Attribute: occi.link.source="/compute/vm01", occi.link.target="/storage/disk03", com.example.drive.interface="ide" I guess built in link categories should be defined for the Infrastructure model (ie. disk, nic and maybe console):) This topic relates to the following one as well: [4] link extensions? It is not clear whether someone could use her own, specific links. The category spec states: "Categories schemes can be extended by providers and users by defining there own (with different mutability) scheme. Those MUST be in a different namespace then those described in the OCCI specification." Hence someone can introduce new Categories within new schemes. But can she introduce new categories within the builtin OCCI namespaces? In order to use user defined links this is mandatory since domain specific links are specified by categories of Link type: "A set of associated attributes defined by the categories of the Link type."

Hi, We need to get the Link stuff fixed - so deadline for any comments is next Wednesday. Have a look at the Wiki for the current writings. If possible we want to discuss the network section of the specification on next week's concall. Proposals and input like the document Gyula wrote are more than welcome. To remind you all: We are trying to have the next revision of the specification done by OGF 30 - So by end of September we need to have all technical stuff fixes so we can focus und editorial stuff. Thanks to everybody for contributing and making this happen!
