Over the course of this summer’s DataONE OPeNDAP effort, a key goal of ours has been the development of two things: new practices for managing provenance tracing within the OPeNDAP framework, as well as reference code for future developers to use as a reference. As of now, our reference code Continue reading Week 9 Update: Wrapping up…
Following last week’s progress on front-end development, I’ve now re-directed my focus toward some needed extensions for OPeNDAP’s code base. To highlight what changes are needed, some background on our provenance designs will be helpful. Based on discussions throughout the summer, our group has settled on a provenance record design Continue reading Week 8 Update
Over the past week, our group’s focus has been on implementation work for OPeNDAP’s provenance browser. The approach we’ve taken relies upon three types of data: Sample provenance records for OPeNDAP’s server processing. Records describing OPeNDAP modules called by the server. Developers responsible for maintaining modules. Each of these three Continue reading Week 7 Update
Following ESIP, I came away with a clearer idea both on what types of demonstration software would be of interest to the OPeNDAP community, as well as how best to modify the OPeNDAP code base for our work. Within the next week, we aim to finish a lightweight implementation of Continue reading Week 6 Update
This weekend, I got the opportunity to travel to Copper Mountain to attend both the DataONE User’s Group meeting as well as the OPeNDAP developer’s workshop. Both events proved to be great opportunities to hear about work being done by other members of the OPeNDAP community, as well as get Continue reading Week 5 Update
Following from our team design discussions last week, a set of mockups for OPeNDAP’s provenance presentation service were developed. These mockups are designed to highlight both how provenance records can be exposed, and how descriptive pages for both OPeNDAP modules and contributors can be presented. The user would start in Continue reading Week 4 Update
On June 9th, Patrick and I met up at RPI to discuss presentation strategies for provenance records in OPeNDAP. When provenance for an OPeNDAP data product is exposed, two things will regularly be present: references to specific OPeNDAP modules and their contributors. Therefore, providing a consumer access to this information Continue reading Week 3 Update
In the past week, I’ve coordinated with Patrick West and Tim Lebo to set up my development copy of the Prizms framework. As mentioned earlier, Prizms is a framework for publishing linked data that will aid in our management of OPeNDAP based provenance records. Additionally, based on a review of Continue reading Week 2 Update
Last Tuesday, the kickoff meeting for Project 5 was held at RPI. For this project, our goal will be to extend the OpenDAP framework – a data access framework widely used in earth and space science – with extensions for provenance tracking. Through developing these extensions, we seek to enable Continue reading Week 1 – Getting up to speed
This summer project is an extension of the existing project at https://github.com/tetherless-world/opendap/wiki. We’ll be updating materials there, and discussing them as appropriate on this DataONE notebook.
