nexB OpenAssets is a tool for inventorying, managing, and monitoring applications, software, hardware, networks, and generally any IT asset. It is designed so that system administrators, IT, and finance can determine what they have, how it is configured, what it is used for, and how much it is being used, so that informed decisions can be made. It complements existing network management software, integrates with a growing number of protocols and tools, and features no-agent discovery and inventory, configuration management including dependencies and correlation, monitoring, and reporting. It makes extensive and innovative use of XML, Xpath, and Xquery.
Sparse is a semantic parser of source files. It's neither a compiler (although it could be used as a front-end for one) nor a preprocessor (although it contains a preprocessing phase). It is meant to be a small, simple, easy to use library. Its function is to create a semantic parse tree for some arbitrary user for further analysis. It's not a tokenizer, nor is it a generic context-free parser. Context (semantics) is what it's all about: figuring out not just what the grouping of tokens are, but what the types are that the grouping implies.
