Publishing at a venue without ACM/IEEE brand? My PhD Supervisor asked me to submit one of my work at an upcoming International Conference. He is amongst the program committee members. I was having a look at its committee members, the Advisory committee etc. It boasts of researchers from reputed Universities- with some of them quite well established (I know some of them personally). Further, the conference is happening for the 6th time. 

However I found it quite strange that they are organizing the conference without any branding of IEEE/ACM etc. behind them. The proceedings of the conference will be compiled on a CD-ROM. This obviously means that if my paper gets accepted there, it is not going to be archived with IEEE-xplore or ACM digital library. Google may index it because they may put the PDFs on the conference's website, but that PDF exists only as long as the website for the conference exists. 

The question in my mind: Is such a publication bad for a PhD student? If I put this work on my CV, nobody can find it on the Internet (except on my personal website or archived on arXiv). Then where is the credibility that work was actually peer-reviewed and published at an International Conference? 

And what about copyright issues? The website says nothing of it. These are a group of researchers from different parts of the world coming together to organize a conference. There is no organization like ACM or IEEE behind them. So I am assuming that the issue of copyright transfers may never arise. Does that mean I can submit this work to other venues as well (since exclusive copyright are never transferred)?

Truly speaking, the only reasons I am going for it is because (1) my Supervisor wants me to, and (2) selected high-quality papers will get the opportunity to submit extended versions to special issue of a SCI journal (which is great for me!). 

p.s.: In case it matters: until the past year, it was being organized as a 'workshop'. This is the first time they are calling it a conference and have a Journal extension. 

p.p.s: My field is Computer Science.
Not being affiliated with an organization such as the IEEE or ACM is not, on its own, a bad sign. For example, what is currently the IEEE Conference on Computational Complexity has decided to end its affiliation with the IEEE and go solo; the Symposium on Computational Geometry likewise just left ACM. STACS is also unaffiliated.

It's not great if the proceedings are only distributed on CD. On the other hand, if you're already going to be preparing a journal version (and you should!), that will completely supersede any conference version, anyway. I would never read a conference version ("extended abstract") of a paper if a full version was available: in my area (theoretical CS), the conference version generally has the proofs missing and the peer review isn't very rigorous.

STACS publishes proceedings through Dagstuhl, which is basically a computer science conference centre in Germany and has close links to DBLP. In this case, copyright is retained by the authors. Note that, regardless of who owns the copyright, most CS conferences won't accept papers which have either appeared at another conference with published proceedings or have been submitted to such a conference. You don't get to double-dip your papers.
