I have been working on this (mostly) annotated collection of  tools and articles that I believe would be of help to both the data dabbler and professional. If you are a data scientist, data analyst or data dummy, chances are there is something in here for you.

I included a list of tools, such as programming languages and web-based utilities, data mining resources, some prominent organizations in the field, repositories where you can play with data, events you may want to attend and important articles you should take a look at.

The second segment (BONUS!) of the list includes a number of art and design resources the infographic designers might like including color palette generators and image searches. There are also some invisible web resources (if you’re looking for something data-related on Google and not finding it) and metadata resources so you can appropriately curate your data.

This is in no way a complete list so please contact me here with any suggestions!

2. PSPP- PSPP is a program for statistical analysis of sampled data. It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most important of these exceptions are, that there are no “time bombs”; your copy of PSPP will not “expire” or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get “advanced” functions; all functionality that PSPP currently supports is in the core package.PSPP can perform descriptive statistics, T-tests, linear regression and non-parametric tests. Its backend is designed to perform its analyses as fast as possible, regardless of the size of the input data. You can use PSPP with its graphical interface or the more traditional syntax commands.
3. Rapid I- Rapid-I provides software, solutions, and services in the fields of predictive analytics, data mining, and text mining. The company concentrates on automatic intelligent analyses on a large-scale base, i.e. for large amounts of structured data like database systems and unstructured data like texts.

4. R Project – R is a language and environment for statistical computing and graphics. It is a GNU projectwhich is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity.One of R’s strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control.R is available as Free Software under the terms of the Free Software Foundation‘s GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS.

Metadata

1. Description Schema: MODS (Library of Congress) and Outline of elements and attributes in MODS version 3.4: MetadataObject
   This document contains a listing of elements and their related attributes in MODS Version 3.4 with values or value sources where applicable. It is an “outline” of the schema. Items highlighted in red indicate changes made to MODS in Version 3.4.All top-level elements and all attributes are optional, but you must have at least one element. Subelements are optional, although in some cases you may not have empty containers. Attributes are not in a mandated sequence and not repeatable (per XML rules). “Ordered” below means the subelements must occur in the order given. Elements are repeatable unless otherwise noted.”Authority” attributes are either followed by codes for authority lists (e.g., iso639-2b) or “see” references that link to documents that contain codes for identifying authority lists.For additional information about any MODS elements (version 3.4 elements will be added soon), please see the MODS User Guidelines.
2. wiki.dbpedia.org : About DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link other data sets on the Web to Wikipedia data. We hope this will make it easier for the amazing amount of information in Wikipedia to be used in new and interesting ways, and that it might inspire new mechanisms for navigating, linking and improving the encyclopaedia itself.
3. Semantic Web – W3C In addition to the classic “Web of documents” W3C is helping to build a technology stack to support a “Web of data,” the sort of data you find in databases. The ultimate goal of the Web of data is to enable computers to do more useful work and to develop systems that can support trusted interactions over the network. The term “Semantic Web” refers to W3C’s vision of the Web of linked data. Semantic Web technologies enable people to create data stores on the Web, build vocabularies, and write rules for handling data. Linked data are empowered by technologies such as RDF, SPARQL, OWL, and SKOS.
