WEBVTT Kind: captions Language: en 00:00:00.880 --> 00:00:04.400 Hello everyone, my name is Alex Kinnaman, the  digital preservation coordinator at Virginia   00:00:04.400 --> 00:00:08.240 Tech university libraries and I'm here to give  you a quick rundown of our work on creating a   00:00:08.240 --> 00:00:13.760 3D preservation model for cross-disciplinary use.  So a bit of background, we have these really cool   00:00:13.760 --> 00:00:18.880 bugs and the library received a CLIR grant for our  project Entomo 3D to digitize the Virginia Tech   00:00:18.880 --> 00:00:22.800 insect collection. These insects are used for  educational purposes but they're very fragile   00:00:22.800 --> 00:00:27.360 and it's difficult to interact with them so we  are using photogrammetry and multiple softwares   00:00:27.360 --> 00:00:31.440 to digitize a portion of this collection in 3D  and the rest in still images to help increase   00:00:31.440 --> 00:00:36.240 interaction with this collection. So how do we  preserve all of these bugs? The goal here is   00:00:36.240 --> 00:00:40.400 reproducibility. I worked with three different 3D  experts on the Virginia Tech campus who work with   00:00:40.400 --> 00:00:45.600 three types of 3D and VR data and formats to  get an overview of what an expert in the field   00:00:45.600 --> 00:00:51.200 would need to open, understand, and manipulate an  unfamiliar data set. Several common risks to 3D   00:00:51.200 --> 00:00:56.880 content that we found were software obsolescence,  large files which are difficult to open the file   00:00:56.880 --> 00:01:01.840 formats support and updates for the popular OBJ  format ceased about 15 years ago, there's a heavy   00:01:01.840 --> 00:01:06.800 reliance on proprietary software and hardware, and  also a lack of community standards, and that it is   00:01:06.800 --> 00:01:12.560 essential that we have documentation on provenance  to ensure open ability and reproducibility. So our   00:01:12.560 --> 00:01:17.280 initial results from these interviews are that  first we will be using X3D as the preservation   00:01:17.280 --> 00:01:22.800 format. X3D is an ISO standard, it's open, it's  not proprietary. We will also be using a combined   00:01:22.800 --> 00:01:26.800 metadata model from various schemas so we can  pick and choose what we can reasonably collect   00:01:28.000 --> 00:01:32.400 we will also be capturing provenance at every  step and capturing granular technical metadata,   00:01:32.400 --> 00:01:36.080 and finally we are beginning to understand  that the purpose of the object determines   00:01:36.080 --> 00:01:39.840 what metadata and documentation is really  necessary for understanding and reproducibility.   00:01:41.040 --> 00:01:46.240 So now I am reaching out to the greater  digital preservation and 3D VR community   00:01:46.240 --> 00:01:51.440 with an IRB-approved research study to investigate  community adopted workflows. We invite any digital   00:01:51.440 --> 00:01:56.160 preservation professionals and those who produce  and or curate 3D and VR content to participate   00:01:56.160 --> 00:02:00.640 in a 15 minute web-based survey. We're really  excited for this feedback and we'll publish the   00:02:00.640 --> 00:02:05.760 anonymized results and our final workflow when it  is implemented. Thank you so much for listening,   00:02:05.760 --> 00:02:09.600 and I hope you enjoyed the sneak peek of the  amazing work our 3D texture artist has done   00:02:09.600 --> 00:02:13.920 on these bugs.
