  • I’ve personally never heard of companies who can produce a paper for you until word got around among my college groupmates. My professor asked me to write a research paper based on a field I have no idea about. My research skills are also very poor. So, I thought I’d give it a try. I chose a writer who matched my writing style and fulfilled every requirement I proposed. I turned my paper in and I actually got a good grade. I highly recommend ⇒ ⇐

After some google searching, I found this service ⇒ ⇐ who helped me write my research paper. The final result was amazing, and I highly recommend ⇒ ⇐ to anyone in the same mindset as me.

  3. 3. engaged citizen What? What?  Explore data portal/catalogs Chunk up data and reassemble into a meaningful argument Share that argument Have others derive work from your findings IntroIntro
  4. 4. Ultimately...Ultimately... goal is to model and share a thought process based on open data IntroIntro has to be  shareable -> open data verifiable -> assessment of authenticity of sources reproducible -> standards-based, open description of process
  5. 5. Preamble : Data standardsPreamble : Data standardsTechTech as the 3rd star of open data, it should be obvious by now... but considering the current state of open data, it's better to rub it in XLS sheets ZIP files a link to a webpage that gathers some data .... are not open data standards!
