Yup

...as implemented by Hibernate.

After quite some time using JPA (Hibernate implementation), trying to map what amounts to legacy (well, that's too harsh--probably should say 'traditional') db schema to JPA entities, which resulted in hours, nay, days of frustration, I finally feel like I understand how to use JPA with Hibernate (though some of the quirks I could do without, or maybe have features implemented).

[Side note: I was reminded that Hibernate was not a cure-all for object access to the database, but that it implemented a subset of everything that could be done. The first thing that comes to mind that is similar is Ruby on Rails and ActiveRecord--you do it their way if you want to use it.]

It all came to me (understanding the docs, etc.) when I finally (!!) decided to let Hibernate build the schema for me. Now it is much clearer.

Should have done this in the beginning.

For the record, I was considering the following, which would be an interesting addition:

• NsaFile that is programmatically accessible from a replication client outside the firewall.
• GUI for replication

Immediate goal: High level, long term.
Long-term goal: more detail of these ideas.
Some of these may be pertinent to other (new) projects outside the scope of work.

• Workspace (à la VOSpace)
• Public Access Layer (à la VOSpace)
• Direct usage of DS by applications
• Full metadata model (types)
• Expand the configuration model
• Integration with DAF
• VOEvent service implementation
• Client (end-user) replication utility
• Analysis Service component
• Calibration Service
• Workflow Service
• Collaboration Service

Modified the blog script to create a tmp-file, then move it afterwards, with permission. The date is created appropriately.

Worked on changing the look of this site. I took the CSS from Andrew Cooke's CompUTE blog (http://www.acooke.org/cute/).

YAB. Why do we need YAB? I have found so much information online that I thought maybe I should at least present my experiences with what I've learned and how I've applied it. Hence, this will probably be mostly about programming. We'll see. Everyone has an opinion.
