.... as all parsing tasks could be moved to a generic XML library, such as expat (Clark, 1998) Bush is another part to reconsider seriously: while useful, it really is somewhat limited in terms of expressivity, compared with the more and more widespread scripting languages, such as Python (Rossum, 1995, Rossum, 1999) and Perl (Wall et al. 1996) One possibility could be to repackage most of the low level Busstop functionality, so it can be called from Python. This would result in a Python based system directly handling any data that can be described by Busstop metadata. And as the Numerical ....

....service environment not yet addressed in our work is the safety of untrusted, third party code. While we have not included a solution to this problem in our current design, nothing in our service environment model precludes the use of type safe languages such as Safe Tcl [10] Java [5] or Python [28] and as such we view this problem as important, yet orthogonal to our current endeavor. As part of our future work, we plan to leverage ongoing work in the active networks research community to incorporate safe languages into our service environment. 2.2 Service Location Before a client can ....

....in large scale deployments; disruptions resulting from such service upgrades can adversely aoeect long running sessions of highly available distributed services. To enable service extensibility, we leverage the trend towards using interpreted languages (such as Java [11] Safe TCL [3] or Python [16]) for distributed services and applications [13] Interpreters for such languages already support or can be extended to support dynamic procedure instantiation: that is, code for a procedure can be installed in the run time environment after a program has started executing, but when, or before, ....

....speci c metrics. 5 Related Work Several areas of work impact the design of a framework for active distributed services: The Design of Interpreted Languages: There exist several type safe languages for programming server to client code migration e.g. Java [11] Safe TCL [3] and Python [16]. Omniware [20] allows conversion of code written in languages like C and C into code fragments; it provides a substrate for interpreting these code fragments. Some of these languages may be more appropriate for implementing ADSs than others. the substrate simply provides a vehicle for ....

....anyway. Using associative arrays in Clanger is just like using any other part of the operating system. This also permits an interpreter to be embedded in almost any application with next to no effort certainly without the need for the ad hoc C wrappers required for languages such as Python [11] or Tcl [5] Furthermore, when a new type is introduced to the system, Clanger will be able to manipulate its values with no new code whatsoever. 3 Method Invocation Clanger s integration with the operating system is achieved through the ability to invoke methods on interfaces. A full method ....

....examples. However, they tend to be quite specialised. None provide both the power to interactively invoke any system interface together with the tight integration with a true general purpose operating system supporting many programming languages. General purpose scripting languages such as Python [11], Perl [12] and Tcl [5] can only be extended by writing compiled code as a wrapper around some operating system functionality. Furthermore, they are geared towards usage in an environment with poor definition of interfaces and almost no modularity (though this is less true of Python) For our ....

....be object oriented programming, strong typing, garbage collection, a remote resource access mechanism, GUI support, and, of course, ease of programming. Based on our investigations and comparison of the best known distributed languages such as Java [GJS96, Fla96] Phantom [Cou95, Cou95a] Python [Ros96], Safe Tcl [Bor94, Ous94] and Telescript [GM95] we selected Java as an implementation environment because it supports almost all of the required properties. Java provides a heterogeneous and distributed architecture, which is well suited for our IMA framework. Java is platform independent since ....
