Not only does one need to give meaning to the join and meet of two bodies, but also to extend the consequent algebra so as to encompass the result of a countable sequence of operations of join or meet; and one should also be able to define the limit of a sequence of bodies. To achieve this goal we propose here to define a body ab initio through the assignment of a probability measure dπ. We realize that π leaves, generally, too much of the texture of the body unspecified; to make up for this deficiency, we suggest the use of appropriate texture measures, reminescent of Tartar's H-measures.9

An outlook is given of faced problems and proposed solutions to fulfil the basic requirements of such "administrative portals". Whereas performance can be deferred to secondary technological improvements, development prospects impose at least protection of data integrity and authentication of communications, besides high architectural scalability, flexibility and interoperability with legacy systems, software platform independence. Moreover, information -distributed in a scaleable manner -has to be widely and easily accessible, consistently available, standardised and structured.

Thus, even before getting tools to manage workflow and to distribute it among subjects over a network, public administration can expect a valid contribution from information technology in modelling meta-procedures, as processes that select and assemble procedures. The effectiveness of results depends on how extensively a wealth of administrative knowledge -often dispersed across different practices and personal experiences -can be implemented into flexible information structures. To this end, special approaches have been tested in describing and classifying the available procedural information: as a result, a standard compliant workflow management system has been designed, which allows to configure a smart interactive procedure builder. A prototype has been validated in various EU countries, that provides enough flexibility in configuration and usage to support operations of public one-stop shops.
