Charge: Our goal is to develop a Universal Materials Database for use by the community of researchers who need materials with low radioactivity for the construction of their experiments. This database will be portable and downloadable with a well-designed data format and high quality interface. It is envisioned to be a reference guide for the low-background community to organize and share data, much like the Particle Data Group (PDG) provides for the particle-physics community.

Goal: Our year 1 goal is to have a working version 1 of the database for use and demonstration to the community at the LRT2013 conference. In year 2 our goal is to polish and refine the database into a well developed tool.

Different data views - tabular view, (interaction columns) [H]

1. some data viewing/manipulation library

Security [H]

1. allow secure use of user interface [H]
2. investigate proper user/admin model [H]
3. implement proper user/admin model [M]

Preferences capability [L]

1. document-based (depends on user model)

Flexible document structure [M]

1. code to handle this [M]
2. position/implementation/storage/upgradability of data structure in code [L]
   1. JL prejudice is not to compartmentalize data structure from the code

Search [H]

1. code needs to know what search services available
2. simple fall-back (view+loop) in case none are available
3. couchdb-lucene where available
4. Cloudant Search (~couchdb-lucene) where available

Data download [M]

1. CSV
2. ROOT
