Datasets – User Contributed Content (USR)

User Contributed Datasets is part of the community driven efforts to provide interesting datasets.

Sim Wei Sung Lincoln and Shahila Syed Ali Shah are students from Temasek Polytechnic who came up with an idea titled “After 12″.
The purpose of this dataset is to offer information about the amenities such as Restaurants, Clinics, Convenient Stores, etc that are opened 24 hours.

Their motivation  came from the understanding that it was troublesome to think about the nearest place to have late supper with friends or the nearest clinic to head for past midnight.

Thus, they came up with the idea of collecting those datasets and build an application that could show the nearest selected amenities within a chosen distance from where they currently are.

Kudos to Lincoln and Shahila from Temasek Polytechnic!

.NET – How do I access a complete list of AXS

public List<AXSEntry> GetAXSSetFromNimbusUSR(string AccountKey,string UniqueUserID)
    {
        System.Net.WebRequest wr=
          HttpWebRequest.Create(
            "http://api.projectnimbus.org/usrodataservice.svc/AXSSet?");
        wr.Headers.Add("AccountKey",AccountKey);
        wr.Headers.Add("UniqueUserID",UniqueUserID);
        wr.Method = "GET";
        WebResponse res = wr.GetResponse();
        string resStr
         = new System.IO.StreamReader(res.GetResponseStream()).ReadToEnd();

        XNamespace atomNS

        List<AXSEntry> results
          = (from item in XElement.Parse(resStr).Descendants(atomNS + "entry")
            let axs = item.Element(atomNS + "content").Element(mNS +"properties")
                select new AXSEntry() {

            }).ToList();

        return results;

Java – How do I access a complete list of movies

public ArrayList<AXS> getAXSs(String accountKey, String uniqueId) {

    StringBuilder strBuilder = new StringBuilder();
    while ((line = br.readLine()) != null) {
      strBuilder.append(line);
      System.out.println(line);

    for (String str : IProperties) {
      AXS axs = new AXS();
