अपाचे कॉमन्स

अपाचे कॉमन्स अपाचे सॉफ्टवेयर फाउंडेशन की परियोजना है, जो पूर्व जकार्ता प्रोजेक्ट के अंतर्गत थी। कॉमन्स का उद्देश्य पुन: प्रयोज्य, खुला स्रोत सॉफ्टवेयर जावा (सॉफ़्टवेयर प्लेटफ़ॉर्म) सॉफ़्टवेयर प्रदान करना है। कॉमन्स तीन भागों से बना है: उचित, सैंडबॉक्स और निष्क्रिय।

कॉमन्स उचित

कॉमन्स प्रॉपर पुन: प्रयोज्य जावा (सॉफ्टवेयर प्लेटफॉर्म) घटकों को बनाने और बनाए रखने के लिए समर्पित है। कॉमन्स प्रॉपर सहयोग और साझा करने के लिए स्थान है, जहां पूरे अपाचे समुदाय के डेवलपर्स अपाचे परियोजनाओं और अपाचे उपयोगकर्ताओं द्वारा साझा की जाने वाली परियोजनाओं पर एक साथ कार्य कर सकते हैं। कॉमन्स डेवलपर्स यह सुनिश्चित करने का प्रयास करेंगे कि उनके घटकों की अन्य लाइब्रेरी (कंप्यूटर विज्ञान) पर न्यूनतम निर्भरता हो, जिससे कि इन घटकों को सरलता से परिनियोजन किया जा सके। इसके अतिरिक्त, कॉमन्स घटक अपने इंटरफेस (कंप्यूटर विज्ञान) को यथासंभव स्थिर रखेंगे, जिससे कि अपाचे उपयोगकर्ता, साथ ही अन्य अपाचे परियोजनाएं, भविष्य में परिवर्तनों के बारे में चिंता किए बिना इन घटकों को प्रारम्भ कर सकें।
