What are the tradeoffs between the various email archiving approaches? Why would you archive anything other than mbox? (although, you need to document how you escape '^From' lines) |

What approaches are there for archiving and preserving databases and what tradeoffs are there between different approaches? Are you looking to archive point in time and/or unchanging databases, or the full history of how it changes over time? Is it just data in tables, or are there conditions, triggers, stored procedures or other logic stored in the database? |

Can someone suggest a good open source document management system? It really depends on just what sort of functionality you need to to do, and how large it's going to need to scale. There's everything from OODT, Fedora, DSpace, etc. You could even use a cloud service like S3 if you need it mostly just for storage. Or you could use something like iRODS as middleware to access multiple storage systems. |

What makes a successful digital scholarship centre? For some of the projects I've worked on, there's some sort of a steering committee composed of the people who would be directly benefiting from the project (in my case as I'm building data systems for scientists, it's 100% composed of scientists). There are members who have some limited experience in managing/building data systems, but their role as a steering committee is solely to set scope & priorities -- they draw on advice from us programmers (estimates of feasibility & time costs), but they're the ones who make the final decisions to set scope / features / priorities. |

What tools are recommended for characterising, assessing or appraising digital content acquired for preservation by an archive? @Ed: It depends on the case. I know of projects where so much metadata was in the files that it broke some programs that tried to read them. And where the metadata was presented in multiple ways but with a minor inconsistancy and you had no way to tell which were derived vs. original. But I have way more examples where the metadata is just not there. (I know what size the image is ... but when it was taken? from which instrument? observing mode? No clue other than knowing how the filenames were encoded ... and the filename wasn't stored in the metadata, just the OS.) |

Not to be confused with FITS (flexible image transport system) which is a scientific file format used by the astronomical (and occasionally the preservation) community for storing images and other multi-dimensional arrays. |

How to encode latitude and longitude in Dublin Core's dc.coverage? And in DSpace? Oh ... and my suggestion to DataCite was for them to pack it all into Subject, with an identifier for the coordinate system used in subjectScheme. (and do the same for the temporal & spectral descriptions, which can also be pretty complex, as you try to explain things recording as they're moving, with red shift, etc.) |

How to encode latitude and longitude in Dublin Core's dc.coverage? And in DSpace? it's a massive can of worms .. I just e-mailed something to the DataCite folks as they had a proposal to support "spatial" (again, they meant geo). But you have RA/Dec for basic astronomy, but to explain it all, you need WCS. Just as an example in solar, we have lat/long, but that's from earth ... the sun rotates so there's carrington lat/long for sun spots, plus polar coordinates for CMEs ... but the telescope pointing is in x/y projections. |

How to encode latitude and longitude in Dublin Core's dc.coverage? And in DSpace? damn them and their geo-centric spatial coordinate system! it's completely useless for anything not on earth or in a geostationary orbit. (although, it does solve the lat/long question) |

Need high-quality young adult book list to compare to YALSA list You could always answer this question w/ the comprehensive list + check 'community wiki' so that others can edit/add to it. (and then mark it as the accepted answer, so it'll show up at the top) |

Where do formal citations in scientific publications originate from? I assume you've read Garfield's 1954 "Association-of-Ideas Techniques in Documentation: Sherpardizing the Literature of Science" and Weinberg's 2004 "Predecessors of Scientific Indexing Structures in the Domain of Religion]. Admittedly, they're more about citation indexes. You might also look to see if any local libraries have Samuel C. Bradford's 1948 Documentation |

What regular expression would match Library of Congress call numbers? as there are only a few links of significance in that discussion (to the Perl, Perl/Python and Java code), you may want to reproduce them here, just in case the intermediary site should disappear. |
